BT5-4608 – PAG150 A/C Oil, 8 oz (R134a Systems)

Description

The BTRAC BT5-4608 PAG150 A/C Oil is a high-viscosity polyalkylene glycol (PAG) lubricant engineered specifically for R134a mobile air conditioning systems, with a focus on GMC and GM compressor applications. This 8-ounce bottle delivers consistent lubrication, strong film strength, and enhanced protection for compressors that require higher-viscosity PAG oil.

PAG150 oil is commonly specified in systems where increased load capacity and oil film stability are required. It provides excellent miscibility with R134a refrigerant, allowing oil to circulate efficiently throughout the system while protecting internal components from wear and heat-related breakdown.

This formulation is compatible with Neoprene, HNBR, and Buna-N O-rings, as well as XH7 and XH9 desiccants, ensuring proper chemical compatibility in modern mobile A/C systems. Because PAG oils are hygroscopic, exposure to air should be minimized to prevent moisture absorption that can negatively impact system performance.

PAG150 A/C Oil – Facts & Industry Stats (SEO Value)

• PAG150 refers to an ISO viscosity grade of approximately 150 cSt at 40°C, making it significantly thicker than PAG46 and PAG100 oils

• Higher-viscosity PAG oils are often specified for larger displacement or higher-load compressors

• PAG oils are used in over 90% of R134a mobile A/C systems worldwide

• Proper moisture control is critical—water contamination above 50 ppm can reduce lubrication effectiveness and accelerate component wear

• PAG oils provide superior oil return characteristics compared to mineral oils in R134a systems

• PAG oil is not compatible with R12 systems and should never be mixed with mineral or ester oils

These properties make PAG150 oil a trusted choice for demanding mobile A/C applications requiring enhanced lubrication stability.
