Post subject:  late OPRV O ring size

After trying to find the O ring size for late one piece OPRV, (part no. 999 707 144 40)  I bought a couple and took some measurements, so here for anyone looking for the info, here are the dimensions,

OD 16mm

ID 12.4mm

Thickness 1.8mm
after checking, there are two O ring sizes which should be OK
1.78x12.42mm
and
1.8x12.5mm
