Volkswagen Golf Service & Repair Manual: O-ring
| These O-rings seal the joints between the individual
components of the refrigerant circuit. |
| Use only seals that are resistant to refrigerant R134a and
its associated refrigerant oils. This is assured by using
genuine replacement parts. |
| Check that diameters -a- and
-b- are correct. |
| Before fitting a seal, coat it lightly with refrigerant oil. |
 Note
| The colour coding of O-rings for R134a refrigerant circuits
has been discontinued. Coloured and black O-rings are used. |
