Theoben Rapid Forum

hopefully some one might know of the size of the O-ring used on the pressure release button the O-ring is green colour I did ring best fittings and asked what the size of the O-ring is so I could order some
told me he would get back to me so far no joy  I could not measure O-ring as it was brittle and broke up

many thanks

You could try our downloads section i`m sure it displays all O-rings used for the rapid range and including sizes.

:)

hello Kernal
had a look but they are only for rapid's the reg tester is made by best fittings .when I gave them a ring I was hoping that they would do spares but they don't

There should be one each side of the button?
Maybe the other one is in good enough condition to remove and measure.

Can't see it being an obscure size....

just had the pin out of mine and the orings are rock hard black NBR
Could pop one out but knowing my luck I'd probably end up in the same boat.

thank you Squinty
for having a look and the down load
