A/C Coupler O-ring: Service and Repair
-
Always use O-rings only once, always replace.
-
Moisten with refrigerant (PAG) oil before installing.
-
Make sure seal is correctly located on the line or in the groove.
-
Handle O-rings only in a clean working environment.
NOTE: Only O-rings which are resistant to R-134a refrigerant and to the relevant refrigerant oil may be installed (only original parts make sure of this).
Such O-rings are colored in order to eliminate any confusion (at present "red" or "violet" See Parts Dept).
