Hw100 leaking

[knightrider]

My hw100 leaks air when the cyclinder is attached and not attached to the rifle.ive changed the small o ring and also the o ring behind the brass part.any ideas what the problem is?

if the cylinder leaks when not on the gun then dip test the cylinder, is the quick fill type ? if so for a wild guess its just the filler valve oring. get that air tight then re attach , if pressure drops then its seals in the breach block. go on hwowners forum theres plenty of advice and pictures to help you out. atb gc..

Stick a balloon over each end of the cylinder and see if one or both start to inflate. That'll tell you where it's leaking from and then you can have the problem rectified. Mine apparently ended up with three seals replaced at the gauge end.

At the gauge end, did you pull the balloon down far enough to cover the fill port? That's where mine was leaking from.

I never bother with this balloon business, check mine in water, bubbles will appear immediately. Dry with cloth and hair dryer, no problems. Think it comes from when I used to wash my SLR in the shower after exercises in the mud, always had the best kept weapon in the squad.
