- Always use O-rings only once, replace.
- Coat the O-rings with refrigerant oil before installing.
- Make sure O-rings are seated properly on pipe or in groove.
- Check the connections on the components and refrigerant lines for damage (even a small scratch can lead to leakage).
- Perform the work under clean conditions (even the smallest deposit such as a hair may cause a leak).
- Only O-rings, that are durable against refrigerant R134a and/or refrigerant R1234yf as well as the applicable refrigerant oil, may be installed. Refer to Parts Information.
The dimensions -a- and -b- are different depending on the component location of the O-ring. Refer to the Parts Information.
