- Replace the seals.
- Coat the seals with refrigerant oil before installing.
- Make sure seals are seated properly on pipe or in groove.
- Perform the work under clean conditions (even the smallest deposit such as a hair may cause a leak).
NOTE:
Only seals, that are durable against refrigerant R134a and/or refrigerant R1234yf as well as the related refrigerant oil, may be installed. These seals are color-coded to avoid mistakes (currently "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 seal. Refer to the Parts Information.
In addition to the color-coded seals, black seals are also installed during production for certain connections.
