Refrigerant Circuit Seals

WARNING: This page is about a different car, the 2018 Volkswagen Jetta, 2017 Volkswagen Jetta, 2016 Volkswagen Jetta, and 2015 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Replace the seals after removing.
Coat the seals with refrigerant oil before installing.
Make sure the seals are positioned correctly on the pipe or in the groove.
Ensure cleanliness when working. Even the smallest contaminant, a hair for example, can cause a leak.
Only install seals that are resistant to refrigerant R1234yf and the corresponding refrigerant oil.

The dimensions -a and b- are dependent on the component location of the seal.
