vacuum pump fitting oring dimensions

[Theiceman]

There is small oring where the fitting for the booster goes right to the pump, Its the one that shrinks and causes the fitting to rattle in place. I have seen this fixed with JB weld but does anyone know the dimensions to said oring ?

thanks

Okay never mind I found out after some searching

it is a Viton 20 mm by 2mm the fitting can be removed and the oring replaced without gobbing JB weld all over your car . unfortunately you have to take the vacuum pump out ot do it properly so you will likely need the 56mm by 2.5mm oring to replace it.

cheers.

BTW I called Audi of Oakville as they have the 56mm oring in stock .... $43.00 .. I told him I wanted the ORING not the whole pump ... he said then thats $356.00
