BT9-4605 – PAG46 A/C Oil, 8 oz (R134a Systems)

Description

The BTRAC BT9-4605 PAG46 A/C Oil is a high-quality polyalkylene glycol (PAG) lubricant designed specifically for R134a mobile air conditioning systems. This 8-ounce bottle delivers reliable lubrication, excellent miscibility with R134a refrigerant, and consistent performance in modern automotive and heavy-duty A/C applications.

Formulated to meet the demands of Ford 10PA, FS10, Seltec TM, and scroll compressors, PAG46 oil helps reduce internal friction, protect compressor components, and maintain efficient system operation. Additionally, it is fully compatible with Neoprene, HNBR, and Buna-N O-rings, as well as XH7 and XH9 desiccants, ensuring safe integration into properly designed R134a systems.

Because PAG oils are hygroscopic, exposure to air should be minimized to prevent moisture absorption. Proper handling is also important, as PAG oils are more abrasive to skin than mineral or ester oils. When handled and stored correctly, PAG46 oil delivers long-term reliability and optimal compressor protection.

PAG46 A/C Oil – Facts & Industry Stats

• PAG46 refers to the oil’s ISO viscosity grade (~46 cSt at 40°C), making it one of the most commonly specified viscosities for automotive and heavy-duty mobile A/C systems

• Over 90% of R134a mobile A/C compressors specify PAG oil rather than mineral oil

• PAG oils provide superior refrigerant miscibility, which helps ensure oil circulation throughout the system

• Moisture contamination above 50 ppm can significantly reduce PAG oil performance—sealed handling is critical

• PAG oils are non-compatible with R12 systems, reinforcing the importance of correct refrigerant matching

These characteristics make PAG46 oil a trusted choice across OEM and aftermarket mobile A/C service environments.
