o-rinbg between the schrader ands the shock pump, which seals the connection butsn't allow the pin on the pump's female thread to physically open the swchrader's stem, meaning the schrader acts as a check valve and will be closed when the pump is removed.

Simple really, find an o'ring that is the same diameter as the valve (6mm), place this in the part that screws onto the valve.

Oh come on, it's really simple - you just need to put an o-ring or similar rubber seal between the schrader and the pump connector, in such a way that the connector's pin cannot physically touch the schrader stem.

um...........
read the posts?
he did explain...
you fill it up, then you press in the tyre valve, and it shoots.
try reading before you post, and if you already have read the posts and still cant figure it out, ask a more specific question.
