Refrigerant Circuit O-Rings
- Always use only once.
- Lubricate with refrigerant oil before installing.
- Pay attention to correct positioning on pipe/in groove.
- Ensure cleanliness when working.
NOTE:
Install only O-rings that are resistant to refrigerant R134a and corresponding refrigerant oil. These O-ring seals are color-coded to avoid mistakes (currently red, light purple and dark purple).
The O-ring dimensions -a- and -b- are different depending on installation location.
In addition to the color-coded O-ring seals, use is also made at the factory of black O-ring seals for certain connections.
