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.

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