O-Rings






A/C Refrigerant System Component Description

O-Rings





O-rings seal connections between A/C system components.

• Always use correct size O-rings (dimensions - a - and - b -).

• Do not reuse O-rings, always replace. Use only new O-rings that are compatible with R-134a refrigerant and refrigerant (PAG) oil on R-134a systems.

• O-rings for use only on R-134a systems may be color coded: red, green, violet or black.

• Lubricate O-rings with the appropriate refrigerant oil before installing (only use PAG oil).
