    I had a slow leak on my Hw100 cylinder, it was leaking from the small atmospheric hole at the front of the cylinder, they have 3 such holes I think in the cylinder.I did the dip test and found the leak.

    HW 100 air leak from valve housing

    Hi everyone, I've had a HW100 for 4 years now & it's developed an air leak.
    When I attach the air cylinder, air begins immediately venting from a small hole on the underside of the valve housing at quite a rate. I have changed the 2.57mm x 1.78mm O ring on inlet valve stem but this has had no effect? The cylinder hasn't been removed from the rifle very often & hasn't suffered any damage. Any thoughts on the cause?

    KR Andy
