Product Description
PAG 150 compressor oil for R-134a heavy-duty A/C systems — high-viscosity polyalkylene glycol for trucks, heavy-duty vehicles, fleet applications, and light HVAC equipment running R-134a. Premium synthetic with excellent film strength, thermal stability, and wear protection under high-pressure operation.
HCPRO Performance PAG 150 is an 8 oz / 237 mL heavy-viscosity automotive A/C compressor lubricant. ISO VG 150 / SUS 300, specific gravity 0.93, flash point 455°F, pour point -31°F, color yellow-clear tint, pH 7. Meets ASTM D445, D2270, D92, D97, D974, D2783, ANSI-ASHRAE 97-1989, and FZG standards. For R-134a A/C systems specifying PAG 150 — heavy-duty trucks, fleet vehicles, certain commercial applications, light HVAC equipment. NOT for R-1234yf, hybrid, or EV compressors.
Who this oil is for
Heavy-duty truck A/C technicians. Fleet maintenance teams servicing commercial vehicles. Auto A/C techs working on full-size SUVs and pickups where OEMs spec heavier viscosity. Service techs on certain commercial refrigeration and light HVAC units running R-134a with PAG 150.
When to use it
During R-134a A/C compressor service when the OEM calls for ISO VG 150. Full compressor refill: 4–8 oz per OEM spec (heavy-duty systems often run higher capacities — check the manual). Top-off after recharge: 1–2 oz per circuit. The right choice for high-pressure or high-load applications.
Why PAG 150 vs PAG 100, PAG 46, or POE
PAG 150 is the heavy-duty choice for high-pressure R-134a compressors. PAG 100 is standard for domestic vehicles; PAG 46 for lighter-duty imports. POE is for modern HFC and A2L refrigerant systems — not compatible with R-134a PAG systems. Running PAG 100 in a PAG 150 system causes premature wear under load.
Single 8 oz bottle, sealed leak-proof packaging, 2–3 year shelf life unopened. Manufactured in the USA to OEM compressor lubricant performance standards.
