O-Ring Seals
These rings seal off the connection points between individual components of the refrigerant circuit.
Only O-rings that are resistant to refrigerant R134a and refrigerant oil must be installed. Make sure they are original replacement parts.
O-ring seals:
-- Always use only once.
-- Make sure diameters -a and b- are correct.
-- Coat with refrigerant oil before installing. Refer to Refrigerant Circuit and the Parts Information.
NOTE:
The color coding of refrigerant circuit O-rings with R134a has been discontinued. Black and colored O-rings are used. Refer to the Parts Information and Refrigerant Circuit .
