Refrigerant Circuit Seals
WARNING: This page is about a different variant/trim than selected.
- 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).
NOTE:
Only O-Rings, That Are Durable Against Refrigerant R134a And/Or refrigerant R1234yf As Well As The Related Refrigerant Oil, May Be Installed. These O-rings can be color-coded to avoid confusion (for example, "red", "light purple" or "dark purple").
The dimensions -a and b- are different depending on the component location of the O-ring seal.
In addition to the color-coded O-ring seals, use is also made at the factory of black O-ring seals for certain connections.
