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. |

-b- are correct. |

| The colour coding of O-rings for R134a refrigerant circuits
has been discontinued. Coloured and black O-rings are used. |
