PAG 46 R134a A/C Compressor Oil – 8 oz, ISO VG 46, Light-Duty Systems

The HCPRO Performance PAG 46 is a light-viscosity polyalkylene glycol (PAG) compressor oil for R-134a A/C systems that specify ISO VG 46 — common on imports, compact passenger vehicles and certain truck applications.

Key features

• ISO VG 46 PAG — matched to OEM specs for light-duty R-134a compressors
• Thermal stability — acid-resistant, non-corrosive synthetic chemistry
• Low pour point (-36°F) and 442°F flash point
• Tested to ASTM and ANSI-ASHRAE 97-1989 lubricant standards
• 8 oz / 237 mL leak-proof bottle — single, 6-pack or 12-pack

Who it's for

Auto A/C technicians servicing imports and compact vehicles where the OEM specifies PAG 46, mobile mechanics doing light-duty recharges, and fleet shops running import inventories.

When to use it

During R-134a compressor service when the OEM calls for ISO VG 46. Full compressor refill: 4–8 oz per OEM spec. Top-off after a recharge: 1–2 oz per circuit. Always confirm in the vehicle service manual — the wrong viscosity grade shortens compressor life.

PAG 46 vs PAG 100, PAG 150 or POE

PAG 46 is the match when the OEM specifies VG 46. PAG 100 suits most standard domestic vehicles; PAG 150 is for heavy-duty systems. POE is for R-1234yf, hybrid, EV, R-410A, R-32 and A2L systems — it is not interchangeable with PAG. For one-step leak detection, choose the PAG 46 UV Dye version.

Manufactured in the USA. 2–3 year shelf life unopened.
