    Leaking FX Cyclone

    Hi.

    My FX Cyclone appears to have a very slow leak, not noticeable whilst out shooting, but the pressure has dropped to about 30 bar after a week in the gun cabinet. I assume a seal has gone somewhere, but which one of many?...where is the best place to start with my repairs?

    Any advise would be much appreciated.

    Graham has covered

    the most likely problem 'O' ring.

    Be very careful with the small inlet valve mechanism any scratches on the tiny piston head (pointed brass part where the tiny 'O' ring fits) may cause further problems.

    If that is the cause, consider buying a plug for the air inlet and a cover for your inlet probe.

    Hi thanks for these.

    Fill probe has had new O rings fitted and fills fine.
    It just the pressure drops slowly once filled.....or am I getting the wrong end of the stick.

    Thanks for the responses.

    As above , the inlet valve is succeptable to getting a bit of crap on it preventing it from closing off properly.
