BT9-4610 – POE A/C Oil, ISO 100, 12 oz (Mobile A/C Systems)

Description

The BTRAC BT9-4610 POE A/C Oil (ISO 100) is a high-quality polyol ester (POE) lubricant engineered for mobile air conditioning systems, including factory-fill and retrofit applications. With a viscosity of 100 cSt at 40°C, this oil provides excellent lubrication, thermal stability, and chemical compatibility across a wide range of mobile A/C compressors.

POE oils are commonly specified for retrofit scenarios, particularly when converting systems or where compatibility with multiple refrigerants and materials is required. This formulation delivers strong oil film strength, reliable oil return, and enhanced protection against compressor wear under varying operating conditions.

BT9-4610 is supplied in a 12 oz container, making it well-suited for service, maintenance, and controlled system charging. As with all ester oils, proper handling is essential to minimize moisture absorption, as POE oils are hygroscopic and should be kept sealed until use.

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

• POE (Polyol Ester) oils are widely used in retrofit A/C systems due to their broad material compatibility

• ISO 100 viscosity oils provide a balance of flowability and load-bearing strength

• POE oils offer better moisture tolerance than PAG oils, though they are still hygroscopic

• Ester oils are commonly used when converting from mineral oil systems to modern refrigerants

• POE oils provide strong lubricity and are often specified in heavy-duty and mixed-application environments

• Exposure to moisture can reduce lubrication effectiveness, making sealed handling critical

These characteristics make POE ISO 100 oil a reliable choice for both OEM service and retrofit mobile A/C applications.
