Fully synthetic, hygroscopic oils based on polyalkylene glycol
Used at the factory by many vehicle and compressor manufacturers in air-conditioning systems with refrigerant R134a, with different viscosities
Advantages/Effect
PAG oils are well miscible with R134a (PAG oils 46 YF and 100 YF additionally with R1234yf) and are suitable for lubrication of most passenger car and commercial vehicle air conditioning systems.
When using PAG oils, care must be taken to select the correct viscosity class (PAG 46, PAG 100, PAG 150). The specifications and approvals of the vehicle manufacturers must be observed.
