O-Ring Seals
These O-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:
- Always use only once.
- Make sure diameters -a- and -b- are correct.
- Moisten with refrigerant oil before installing.
NOTE:
The color coding of refrigerant circuit o-rings with R134a has been discontinued. Colored and black O-rings are used.
