    Crosman 150 Valve stem seal ?

    I’m hoping someone can help please. I have a Crosman 150 pistol which I have renewed the seals in. It still leaks slowly from the barrel which I believe is the valve stem seal. I can’t find anyone who does a replacement that will post to the U.K. I emailed Mac1 Airguns who said he could ship to the U.K. but after emailing him again (twice) he’s not got back to me
    I’m hoping someone on here has maybe had the same problem and can help.

    Many thanks

    Lawrie will probably ask you to just send the valve. Taught me his system of core cutting them out on the lathe and parting off with a scalpel. He also seats the seal back in the stem in the correct manner.

    if you haven't access to a lathe you can make them with hole punches I use urethane crosman cart seals that I trim to fit
    the seal replaces same as a xs 78/79 punch stem out of brass part remove old seal fit new one them press stem back in I then spin in lathe and square up
    I have also made a new body from ptfe or carbon filled ptfe but it's a bit too hard a seal for cos pressure really

    Just wanted to say a big Thank You to all who helped with my question. I’ve received the valve back from Lawrie and he’s done an outstanding job on it. It’s now shooting better than ever so thanks everyone and Thank You Lawrie 😁

    Merry Christmas
