Refrigerant Circuit Seals
- 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:
Install only O-rings that are resistant to refrigerant R134a and corresponding refrigerant oil. The O-ring seals are color-coded to avoid mistakes (currently "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.
