Refrigerant Circuit Components: O-Ring
WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
- All components of the refrigerant circuit submitted for quality observation are always to be sealed (use original sealing caps of original part).
- Replace damaged or leaking components of refrigerant circuit. Refer to COMPONENTS, REPLACING .
- To date, the original parts (compressor, reservoir, receiver/dryer, evaporator and condenser) have been filled with nitrogen gas. This charge is being gradually discontinued. There is little or no pressure equalization when removing the sealing plugs from the original part.
These O-rings seal off the connection points between individual components of the refrigerant circuit.
Only O-rings that are resistant to refrigerant R134a and the associated refrigerant oil may be used. Make sure they are original replacement parts.
O-ring:
- Always use only once.
- Make sure diameters -a and b- are correct.
- Coat with refrigerant oil before installing.
