Trane OIL00037 is a refrigeration and compressor oil that Trane publishes in its own parts catalogue under the product name OIL; REFRIGERATION, R-134, GRADE 68, 1 GAL. Trane designates the oil Grade 68, which is the ISO VG 68 class and the ISO VG 68 band (61.2–74.8 cSt at 40 °C) defined by ISO 3448. It is the R-134 grade in the Trane oil range, published at Grade 68 in a one-gallon container.
We manufacture and supply refrigeration and compressor oils at our own blending plant in Foshan, China. For this grade our equivalent is QSL-68H. It ships from Guangzhou Port, which is next to the plant. There is no fixed minimum order — it is confirmed per order, because a single can and a full container load are both workable and the figure moves with the pack size, the quantity and the destination. Delivery is on any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — and payment is on any commonly used method, including T/T, L/C and PayPal.
QISHANR is a refrigeration oil manufacturer and wholesale supplier, and this grade is supplied in bulk to distributors, HVACR service companies and compressor OEMs worldwide.
Trane OIL00037 is supplied on published terms: the specification, the price terms, the payment terms and the documents are the same for every buyer, and they can be quoted without a site visit. The minimum order is deliberately left open, because it is judged case by case: the part number, the quantity, the pack size, the shipping terms and the container load all move it, so a single can and a full container load are both workable and neither is treated as the normal case. Send us the chiller model, the part number on the nameplate and the destination port, and those three turn the table below into a firm quotation. Documents and lead time work the same way on every order: the technical data sheet and safety data sheet come with the quotation, and the certificate of analysis for the delivered batch comes with the shipment. This grade is supplied wholesale and in bulk — to distributors, HVACR service companies, compressor OEMs and private-label buyers — as well as in single packs and sample quantities.
| Item | Terms for Trane OIL00037 |
|---|---|
| Minimum order quantity | Not a fixed figure — confirmed per order, because it is judged case by case: the grade, the pack size, the quantity, the shipping terms and the container load all move it, so a single can and a full container load are both workable |
| Payment terms | Any commonly used payment method — T/T, L/C, PayPal and every other option — confirmed with the order |
| Price terms | Any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — quoted against your destination port |
| Supply ability | 1,000 pieces per year on this grade, at our blending plant in Foshan — this is the figure for our equivalent, not the annual capacity of the plant |
| Origin | The original Trane product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original Trane OIL00037 oil, or QSL-68H (our own ISO VG 68), manufactured at our blending plant in Foshan, China |
| Who buys this grade | Distributors and resellers who stock refrigeration oil, HVACR and refrigeration service companies, chiller maintenance contractors, and buyers who need private-label or own-brand packing. Wholesale and bulk orders are the norm; trial and sample quantities are also supplied. |
| Grade confirmation | Send the chiller model, the refrigerant and the part number stamped on the nameplate. Trane publishes this part number as Grade 68, and we confirm that it is the right grade for your machine before quoting |
| Viscosity | Grade 68 as Trane designates it, which is the ISO VG 68 class — the ISO VG 68 band (61.2–74.8 cSt at 40 °C). The class is quoted exactly as the manufacturer designates it |
| Pack size | The manufacturer publishes this part number as 1 gal. We supply the pack format you need, and custom pack formats are available as a quotation item. |
| Documents issued with the order | Technical data sheet, safety data sheet, and a certificate of analysis for the delivered batch |
| Handling and storage | Store sealed, away from direct sunlight, and keep the container closed between top-ups. Never mix different oil types, brands or additives. Trane's own position on additives is explicit: no additive has ever been endorsed or approved by Trane, and the manufacturer states that Trane oils are the only oils approved for use in its equipment. |
Supply ability is stated for this grade rather than for the plant as a whole. It is not the annual capacity of the blending plant.
A lubricant order is rarely only a lubricant order. The buyer is usually solving a grade question, an import documentation question, a freight question and a packaging question at the same time — often across more than one product family. Those are the parts of the job we take on, and they are handled by the same team that quotes the oil rather than passed to a third party.
We are a manufacturer rather than a reseller, which is what makes that possible. The blending plant in Foshan, Guangdong runs at 6,000 tonnes a year and has been producing lubricants for more than ten years, so the answer to most of the questions below comes out of our own production and our own paperwork.
| What you are dealing with | What we do about it |
|---|---|
| The nameplate names a part number and you need to know what it is equivalent to | Send us the chiller model, the refrigerant and the part number on the nameplate. Trane publishes this part number as Grade 68, so it can be matched on the ISO VG 68 class rather than on a description, and we confirm the match in writing before you order. |
| You need the grade, not a catalogue description | Every figure on this page is traceable to a document published by Trane, and the sources are linked at the foot of the page. |
| You are buying alongside other oils and want them on one order | Refrigeration oils are the core of our business, not the whole plant. The same lines produce air compressor oils, vacuum pump oils and general industrial lubricants, and a mixed enquiry can be quoted, packed and shipped together rather than split across suppliers. |
| You need documentation for customs or for a tender | CE, CO, MSDS and transport certification are issued as standard documents with an export order. Tell us at the enquiry stage which certificate the destination requires and we compile the file with the quotation rather than after the shipment. |
| You are changing a machine over from another oil | Trane's own instruction is never to mix different oil types, brands or additives, and the manufacturer states that gauges and recovery equipment should be dedicated to a particular refrigerant family rather than shared. Where a machine is being changed over, the old charge is drained and the circuit flushed and evacuated rather than topped up. Tell us what is coming out and what is going in, and we will confirm the changeover procedure with the oil. |
The point of this list is that the questions are answered before the order rather than after it. If you are unsure which of them applies to you, describe the system and we will tell you what we need.
Grade confirmation comes before pricing, because Trane's part numbers separate oils by both grade and refrigerant family, and mixing the families is the mistake that costs a compressor. The sequence is the same whether you are buying one can or a full container:
If you already know the part number and only need a price, send the quantity and the destination port and we will quote directly.
Trane publishes this part number as a catalogue item, and the table below reproduces what the manufacturer states for it — the official product name, the viscosity designation and the refrigerant — with the source of each row. The grade is quoted on the ISO 3448 scale because Trane's own grade designation is 68, which is the ISO VG 68 class.
| Property | What Trane publishes | Source |
|---|---|---|
| Official product name | OIL; REFRIGERATION, R-134, GRADE 68, 1 GAL | Trane Supply — official parts catalogue (part number OIL00037) |
| Viscosity designation | Grade 68 — the manufacturer designates this oil Grade 68, which is the ISO VG 68 class defined by ISO 3448 | Trane Supply — official parts catalogue |
| ISO viscosity grade | ISO VG 68 — derived from the manufacturer's own grade designation, and the ISO VG 68 band (61.2–74.8 cSt at 40 °C) defined by ISO 3448 | Derived |
| Refrigerant | R-134 | Trane — Trane Recommended Oil (commercial HVAC help centre) |
| Pack size and part number | 1 gal container (part number OIL00037) | Trane Supply — official parts catalogue |
Where a value is published by the manufacturer, the source row shows which document it comes from. The viscosity designation is quoted exactly as Trane writes it, because on this range the manufacturer states the grade in its own product name rather than as a measured figure.
The decisions on this part number are made on the manufacturer's designation and on the machine. These are the points that matter.
| Parameter | Position for Trane OIL00037 | What it means for the order |
|---|---|---|
| Viscosity designation | Grade 68 | This is the manufacturer's own designation, taken from the product name in its parts catalogue, and it is the figure a Trane parts order is matched on. |
| ISO viscosity grade | ISO VG 68 — ISO VG 68 band (61.2–74.8 cSt at 40 °C) | The class is what a replacement is compared on, and it is why a buyer looking for an ISO 68 grade is pointed at this part number. The class is quoted as the manufacturer states or designates it. |
| Refrigerant | R-134 | The refrigerant family is the figure that separates the oils that must never be mixed, so it is checked before the part number is confirmed. |
| Grade substitution | Check the nameplate first | Trane's own article ends with the instruction to verify the oil type stamped on the chiller nameplate, and the same instruction is repeated for the equipment covered by its oil bulletin. |
Trane publishes the designation for each part number in this range, and the table above is built on it, because it is what the parts order is matched on.
Trane's oils are separated by the refrigerant family and by the compressor starter on the unit. The table shows the range as Trane publishes it, with this product marked: the official product name, the ISO 3448 position, the refrigerant, and the equipment the manufacturer lists.
| Part number | Trane's official product name | ISO 3448 position | Refrigerant | Equipment the manufacturer lists |
|---|---|---|---|---|
| OIL00015 | OIL; COMPRESSOR, 300 SUS | Designated 300 SUS | R-22 | RTHA / RTHB R-22 water-cooled chillers on standard-temperature duty; DX-evaporator R-22 chillers; Pueblo-built R-22 scroll chillers. Superseded by OIL00031. |

Product names are reproduced from the Trane Supply catalogue, which is the parts document a Trane service contractor works from. OIL00311, OIL00315 and OIL00317 are the same oil published in three pack sizes.
If this part number is not the one you need, the sections below show where it sits against the rest of the Trane range and against the oils we manufacture ourselves, so a substitution can be checked before it is ordered.
| Brand | Grade | Viscosity position | Note |
|---|---|---|---|
| Qishanr | Polyol ester (POE) refrigeration oil | QSL-68H — our own ISO VG 68 grade | Our own equivalent, blended in Foshan, China, and named here rather than described: QSL-68H |
| Trane | Trane oil range | 300 SUS to ISO 68 | The full published range from the same manufacturer; Trane OIL00037 is the R-134 grade in the Trane oil range, published at Grade 68 in a one-gallon container |
| Trane | Trane OIL00049 | Grade 68 | Another part number in the same range, published with its own designation |
| Trane | Trane OIL00048 | ISO VG 68 | Another part number in the same range, published with its own designation |
A substitution should be made on the refrigerant family and on the measured viscosity at 40 °C, not on the part number alone. Trane's own instruction is that its oils are the only oils approved for use in its equipment and that no additive has ever been endorsed or approved, so any equivalent is quoted as an alternative rather than as an approved replacement.
Trane publishes this part number with the grade in the product name: OIL; REFRIGERATION, R-134, GRADE 68, 1 GAL. The name states Grade 68, and 68 is one of the discrete classes defined by ISO 3448, so the grade is the ISO VG 68 class — the ISO VG 68 band (61.2–74.8 cSt at 40 °C). This page keeps Trane's own wording and states the ISO class alongside it rather than replacing one with the other.
The reason the class matters more than the brand on a chiller oil is that the compressor loads its oil in several places at once. The bearings and the shaft seals rely on the working viscosity to carry load, the compression element relies on it to seal, and the oil separator relies on the oil behaving predictably across the whole temperature range. A grade that is one ISO step away is not a small difference in a machine that was designed around a particular film thickness.
The oil in a chiller is chosen from the unit, not from the container size. Trane separates its oils by refrigerant family first and by grade second, which is why the same compressor family takes different part numbers depending on the starter fitted and why the manufacturer's article repeats the instruction to verify the oil type stamped on the nameplate.
The figure to work from is the part number on the machine and the refrigerant it holds. That is the point at which we confirm the grade against the published data before quoting, and it is also why this range carries more than one part number for what looks like the same duty.
Every figure on this page comes from a document published by Trane. Where the manufacturer states a value in its own product name, the name is reproduced in full rather than paraphrased, because on this range the product name is the specification.
It also means a buyer can check a figure rather than take it on trust: where a value is published, the source column shows which document it comes from.
ISO 3448 does not define a continuous scale of viscosity. It defines a series of discrete classes, each a band of permitted viscosity at 40 °C — ISO VG 68 band (61.2–74.8 cSt at 40 °C) is the band this part number is assigned to — and a grade is assigned to a class on its measured or designated figure.
Trane designates this part number Grade 68, and 68 is one of the class numbers the standard defines, so the class is quoted here as the manufacturer's own designation. What a buyer should match, in the end, is the class and the refrigerant family: the class is the figure the compressor was designed around, and the refrigerant family is the figure that decides which oils must never be mixed.
Trane's part numbers separate oils by refrigerant family, and the manufacturer states plainly that its R-22 oils and its R-134a oils must never be introduced into each other's systems. A quotation that skips the part number check is a price for a product that may not fit the unit it is going into, and the cost of that mistake is a compressor rather than a drum of oil.
So the sequence is fixed: send the chiller model, the refrigerant and the part number stamped on the nameplate, and we confirm the grade against the manufacturer's published data before the price is issued. That is also what makes the specification comparable on a page like this one, because every figure is tied to a published document rather than to a description.
We manufacture lubricants at our own blending plant in Foshan, Guangdong, which runs at 6,000 tonnes a year and has been producing for more than ten years. That is what allows us to quote a grade at this class from our own line (our QSL-68H) against the Trane specification, and to hold stock on the grades we list rather than promising on behalf of a third party.
It also means the answer to a question about the oil comes from the plant rather than from an intermediary. If you need the grade matched to a chiller model, or to know which documents come with the shipment, tell us at the enquiry stage and we will confirm it against your destination rather than leave it until the order is placed.
Alongside the refrigeration oils the same plant produces air compressor oils, vacuum pump oils and general industrial lubricants, so a mixed enquiry can be quoted, packed and shipped as one shipment rather than split across suppliers.
A: There is no fixed minimum order — it is confirmed per order, because it depends on the pack size, the quantity and the destination, and a single can and a full container load are both workable. The manufacturer publishes this part number as 1 gal, and custom pack formats and private-label artwork are available as a quotation item, so if your own label has to go on the container, say so when you enquire and it is quoted as part of the project rather than added afterwards.
A: Trane OIL00037 is a refrigeration and compressor oil that Trane publishes in its own parts catalogue under the product name OIL; REFRIGERATION, R-134, GRADE 68, 1 GAL, . Trane designates the grade 68, which is the ISO VG 68 class, and the manufacturer's own article sets out which chillers take which part number.
A: Both are part numbers in the same Trane oil range but they are separated by the refrigerant family and the equipment the manufacturer lists. Trane OIL00037 is published as Grade 68 for R-134, while Trane OIL00049 is published as Grade 68. They are not interchangeable, and on this range mixing the refrigerant families is the failure mode the manufacturer warns about. Send us the chiller model, the refrigerant and the nameplate part number and we will confirm which of the two matches the machine.
A: Trane publishes this part number for R-134. The refrigerant family is the first thing Trane separates its oils by, which is why the part number and the refrigerant are confirmed together rather than one at a time.
A: Yes. Trane designates the grade 68, and 68 is one of the class numbers defined by ISO 3448, so the grade is the ISO VG 68 class — the ISO VG 68 band (61.2–74.8 cSt at 40 °C). The official designation is kept alongside it on this page. Match on the class and on the refrigerant family as well, because those are what the machine was built around.
A: No. Trane's own instruction is never to mix different oil types, brands or additives, and the manufacturer states that its oils are the only oils approved for use in its equipment and that no additive has ever been endorsed or approved by Trane. Where a machine is being changed from one oil to another, the changeover is carried out as a changeover rather than a top-up: the old charge is drained, the circuit is flushed and evacuated, and the new charge goes in clean. Confirm the changeover procedure with us before the system is charged.
A: Trane publishes the part number as a catalogue item: the official product name, which carries the viscosity designation, the oil type and the pack size; the refrigerant and the equipment it goes into, from the manufacturer's recommended-oil article; and, where applicable, the part number that supersedes it.
A: Yes. Private-label artwork and custom pack formats are a normal quotation item, and the container is packed at our plant in Foshan. Tell us at the enquiry stage that your own label is required, and the artwork and the pack are quoted together with the oil rather than added afterwards.
A: Store it sealed, away from direct sunlight, and keep the container closed between top-ups. Never mix different oil types, brands or additives, and do not decant into an unlined steel drum where the oil can pick up rust and moisture.
Every figure on this page is taken from a document published by the brand owner rather than from our own measurement, so each one can be checked before you buy. This is the set of sources, with what each one establishes.
| Source | What it establishes |
|---|---|
| Trane — Trane Recommended Oil (commercial HVAC help centre) | The manufacturer's own statement of which oil goes into which chiller. It establishes the part-number map across this range: RTHA and RTHB R-22 water-cooled chillers nameplated for Oil 15 or Oil 31; every R-22 chiller built at Trane-Pueblo charged with Oil 31 regardless of nameplate; RTHC, RTWD and RTAC chillers on Oil 48 without exception; RTHD chillers split by starter between Oil 48 and Oil 315; RTAE and RTAF on Oil 315; and the Pueblo-built R-22 scroll chillers on Oil 31 or Oil 15. It is also the source of the compatibility warning and of the manufacturer's position on oil additives. |
| Trane Supply — official parts catalogue, part number OIL00037 | The official product name for this part number: OIL; REFRIGERATION, R-134, GRADE 68, 1 GAL. It is the source of the viscosity designation, the oil type and the pack size quoted on this page, and of the supersession where one applies. The full Trane Supply oil listing carries the same names for the rest of the range. |
| ISO 3448:1992 — Industrial liquid lubricants — ISO viscosity classification | The standard that defines the discrete viscosity classes at 40 °C. The class quoted on this page (ISO VG 68, the ISO VG 68 band (61.2–74.8 cSt at 40 °C)) comes from that classification, and it is the reason the grade is compared on a class rather than on a grade letter. |
Where a value is published by the manufacturer in its own product name, the name is reproduced in full so the value can be traced to the catalogue entry rather than treated as a general property.
This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
Trane OIL00037 is quoted on the part number, the pack size and the destination port rather than on a list price. Send your chiller model, the refrigerant, the part number stamped on the nameplate and the quantity you need. We will confirm the grade against the manufacturer's published data — including whether your machine takes this part number or the one next to it, and which refrigerant family it belongs to — and come back with pricing, pack size and lead time. A technical data sheet and safety data sheet come with the quotation, and we can quote our own equivalent side by side so the comparison is on landed cost.
