Bought a Rock Shox pump about 10 months ago, which is now failing to seal properly (air escaping from the pink threaded insert).
Can’t find an ‘O’ ring of the correct size, so it’s going back for a refund. Been used about a dozen times.

Anyone suggest a replacement, needs to handle up to 135psi for a Reba and about 35psi for a set of Bombers.
