O ring dimentions

[royblackburn1@btinternet.]

Hi all, are the inner and outer dimentions  the same for both Orings 68-0588 for a A65 three branch oil junction/manifold thanks Roy

I'm sure they are supposed to be but with parts of this vintage, best to measure.
You have a leak?

Changing from a 2 to 3 branch one of the O ring recess's on the 3 branch looks slightly larger, Roy

I bought a bag of 100 each of two sizes o-rings for this purpose from a large US hardware vendor.
PM me your address and I'll drop a few in an envelope for you.

Thanks for the offer will use new ones I had bought from Drags and hope I don't have to PM you, Roy

Sure, good luck!
It can be a tricky spot to leak proof.
