PAG oil is non-toxic and possesses low volatility, minimizing the risk of atmospheric release during service. This miscibility prevents the refrigerant from separating and causing lubrication starvation at the compressor, which is the primary cause of catastrophic AC failure.
Where to Buy PAG Oil for R134a: Essential Guide
Selecting the incorrect lubricant can lead to immediate component failure or gradual performance degradation, making knowledge of compatibility non-negotiable. When adding PAG oil, employ the injection valve method or the weighing method to ensure the exact amount specified for the compressor is utilized, preventing performance issues caused by dilution or starvation.
Always use a vacuum pump capable of achieving a deep vacuum to remove air and moisture prior to charging. Consequences of Incorrect Lubricant Use Substituting PAG oil with alternatives like mineral oil or alkylbenzene (AB) oil in an R134a system is a critical error with cascading effects.
