My 2240 is leaking co2 every time I fire it, and I think I have narrowed it down to the seal on the valve face where the co2 cart comes in contact with the valve face. Is there a readily available o-ring or neoprene washer at the hardware store that is the right size to replace that seal, or do I need to go through the hassle of contacting Crosman and getting a new one? I am trying to get this 2240 up and running so I can sell it to help fund a P-rod, so the sooner the better!
Thanks in advance,
Chris

Contact an airgunsmith for the seal. Don't know where you are, but here are a few that could supply the part quicker than Crosman.

... if the valve face seal were bad, it would leak all the time once the caplet was punctured, firing or not.

Sounds more like the stem seal is failing to seal immediately after each shot, if so it will leak from the breech or barrel.

you're scared ? go get a dog ... I'd rather die standing than live on my knees

Where are you, and what do you want for it as-is ?

...so I heated it up and removed it. Is it possible to get a new seal from Crosman, or do I need to order the whole valve stem? Or, even better yet, is there an o-ring I can get at the hardware store that will do the job?
Thanks,

...and I think I am going to fix it before selling it. It needs a new valve stem seal. It has several mods, so I was thinking $110 when it's up and running.

... by chucking the stem in a cordless or drill press and spinning it at low speeds while "shaving" the old seal surface with a one edge blade or exacto knife to create a new even surface.

I have saved 4 out of 5 seals this way, but too late if you heated/removed the old seal. O-rings won't hold up for long.

Just toss it & order a new stem.

Replace all the seals and valve stem now. Don't try to fix one thing only to have to hunt down the next leak somewhere else while trying to remember what seals are newer and which ones are older.
