Refrigerant Circuit Seals
WARNING: This page is about a different variant/trim than selected.
- Always use O-rings only once and then replace.
- Coat the O-rings with refrigerant oil before inserting.
- Make sure the O-rings are seated properly on the pipe or in the groove.
- Perform the work under clean conditions (even the smallest amount of contamination, 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"). Refer to the Parts Information.
The dimensions -a- and -b- are different depending on the component location of the O-ring. Refer to the Parts Information.
In addition to the color-coded O-rings, black O-rings are also installed at the factory for certain connections.
