DENSO ND-OIL 9 is an ISO VG 100 double-end-capped polyalkylene glycol (PAG) compressor oil for automotive air conditioning systems that run on R134a. DENSO Corporation manufactures the oil in Japan for Through Vane, Through Vane Scroll and scroll compressor types, including the TV08, TV12, TV14 and SV06 series.
DENSO ND-OIL 9 is a synthetic PAG 100 lubricant specified for R134a automotive A/C compressors. The double-end-capped PAG base resists moisture pick-up better than an uncapped PAG, which matters in a service environment where a can may be opened, used partially and resealed. Measured properties include a kinematic viscosity of 95 mm²/s at 40 °C, 11.8 mm²/s at 100 °C, a viscosity index of 114, a pour point of −40 °C and a flash point of 220 °C by the Cleveland open cup method. Density is 995 kg/m³ at 15 °C, and dielectric strength is 75 kV per 2.5 mm.
The viscosity grade is the deciding factor when choosing within the ND-OIL family. ND-OIL 9 is the PAG 100 grade; DENSO specifies the lighter PAG 46 grades for swash plate and piston compressors, and a POE oil for electric compressors in hybrid and EV systems. Matching the grade to the compressor type is the point of the series.
DENSO ND-OIL 9 is used in independent and franchise workshop A/C service on Japanese-built vehicle platforms. DENSO lists automotive A/C systems in Toyota, Honda, Mazda, Mitsubishi, Subaru and Nissan vehicles as the application set for the ND-OIL series.
When a Through Vane or scroll compressor is replaced on an R134a system, ND-OIL 9 supplies the PAG 100 charge the service record calls for. The 250 ml can suits a single-vehicle job.
After a system flush, fresh PAG 100 replaces oil lost with the recovered refrigerant. Using the specified grade keeps compressor lubrication within the design viscosity range.
Workshops running repeat R134a A/C work take the 1 litre can, which covers multiple vehicles without opening a new seal for each job.
Where a service sheet lists Sanden SP-10, SP-20, Sunoco Sunice PB 100 or a generic double-end-capped PAG 100, ND-OIL 9 is the DENSO-branded equivalent grade to quote.
Before you order: confirm the refrigerant is R134a and the compressor is a Through Vane, TVS, scroll or SV06 type. R1234yf systems and electric compressors take a different ND-OIL grade, listed in the compatibility table below.

| R134a, Through Vane Scroll (TVS) | Compatible | — |
| R134a, scroll type and SV06 series | Compatible | — |
| R134a, swash plate / piston type | Not compatible | DENSO ND-OIL 8 (PAG 46) |
| R134a, electric compressor (hybrid / EV) | Not compatible | DENSO ND-OIL 11 (POE) |
| R1234yf systems | Not compatible | DENSO ND-OIL 12 (PAG 46) |
| R12 systems | Not compatible | DENSO ND-OIL 6 (mineral, obsolete) |
The ND-OIL series splits by oil chemistry, refrigerant and compressor type. The product images on this page show the ND-OIL 9 can first, followed by ND-OIL 11 and ND-OIL 12 cans as series packaging references. Read this table before ordering from a photograph.
| Grade | Oil type | Refrigerant | Compressor type |
|---|---|---|---|
| ND-OIL 8 | PAG 46 | R134a | Swash plate / piston type |
| ND-OIL 9 (this product) | PAG 100, double-end-capped | R134a | Through Vane, TVS, scroll, SV06 |
| ND-OIL 11 | POE | R134a | Electric (hybrid / EV) |
| ND-OIL 12 | PAG 46 | R1234yf | Swash plate / piston type |
ND-OIL 9 corresponds to the double-end-capped PAG 100 grade listed under several other designations. Quote any of the following and the matching DENSO grade is ND-OIL 9.
| Package | Format | Typical use |
|---|---|---|
| 250 ml can (8.5 fl oz) | Sealed metal can | Most common retail size; single-vehicle compressor service |

Request ND-OIL 9 QuoteDENSO ND-OIL 9 is an ISO VG 100 double-end-capped PAG compressor oil made in Japan by DENSO Corporation for R134a automotive air conditioning compressors of the Through Vane, TVS, scroll and SV06 types.
No. ND-OIL 9 is compatible with R134a only. For R1234yf systems, DENSO specifies ND-OIL 12, which is a PAG 46 grade.
No. Swash plate and piston type compressors take DENSO ND-OIL 8 (PAG 46). ND-OIL 9 is the PAG 100 grade for Through Vane, Through Vane Scroll, scroll and SV06 compressors.
It is ISO VG 100, referred to as PAG 100. Its kinematic viscosity is 95 mm²/s at 40 °C and 11.8 mm²/s at 100 °C, with a viscosity index of 114.
ND-OIL 9 is supplied in a 250 ml sealed metal can, which is the most common retail size, and in a 1 litre can for workshop and bulk servicing. Include your quantity and destination in the inquiry for current regional availability.
For PAG grades used in HFC and HFO refrigeration duty, compare the Qishanr QSL-PAG46 ISO VG 46 PAG lubricant and the Qishanr QSL-PAG68 ISO VG 68 PAG lubricant. For industrial PAG compressor duty rather than automotive A/C, see Frick PureOil #12B PAG compressor oil.
