The silicone washer -B- and seal -C- have different functions: the silicone washer -B- protects the threaded connection (if equipped and necessary due to the assembly design), and the seal -C- seals off the refrigerant circuit. For additional information about the seals. Refer to SEALS .
This illustration shows a sensor -A- that is screwed into a refrigerant line -D-.
