AS2260XT co2 seal

[melvin]

I recently bought a AS2250XT and I installed the 88 gram co2 and it leaked out completely which was a frustrating experience.

Looks to be missing the co2 seal. I did my research and called Crosman and they haven’t carried that seal for 7 years.

Anyone have any ideas?  I really would like to start shooting this.

Thanks.

I think a -112 o-ring should work. Pretty sure that's the one that's in the hammerli 850 fitting.

Rich Thankyou so much. I will order some right now. I appreciate it.

Lowes or HD carry Danco and I think that would be a #10 if you wanted to pic them up local. they are 1/2"ID x 11/16"OD

I just ordered 5 of them. Pretty excited to not leak 9 dollar 88 grams again.

Well that didn’t work. Haha. Any more ideas??

What happened? Shohld be the correct size. Wrong material or hardness?

Or is you're one of the ones that doesn't use an o-ring, but a flat seal in bottom?

The o ring seems to big.

I’m not sure. It seems as though there is a notch for the o ring in the fitting.

What was there was so degraded that I could not tell what the material was.

The person I bought it from said he got it new 15 years ago.   I don’t know enough about these to know if the used o rings or flat washers back then.

Are you sure it is leaking from that spot/seal or are the valve seals leaking or valve steam leaking? I am sure there is more than one place it could leak from.

The oring will "seem" big, but I was able to use a punch and push it down into the "groove" in bottom.

Ok I will mess with it in a bit.

It’s such a large leak where the 88 gram attaches that I wouldn’t be able to check for other leaks yet. I would not be surprised if they was more leaks but this is the first thing I need to straiten out.

Also whatever seal belongs there is clearly missing completely.

I don't have any experience with the AS2260XT but I would try to replace all the seals at once instead of potentially wasting a 88gr for each seal. Hopefully someone can tell you if there are current part numbers for like seals that are obtainable. Many airguns that Crosman doesn't sell seals for anymore they use those same seals in current airguns still so if you know the current part number of the seal you can still get it from them.
It is "funny" that the manual page says they have parts for the AS2260XT still so I guess they haven't updated that in seven years.

I would like to replace all the seals. I was hoping I would bump into someone who loved these guns on here and help me out with what I need for the rebuild.

GMAC stocks a kit but it’s unavailable. :/

I have had my eye out for one for a few years but haven't been able to get one yet.

Looks like GMAC has some individual seals and so does JGAIRGUNS https://www.jgairguns.biz/as2250xt-c-78_89_132/

[melvin]

I did notice GMAC had some random ones. I will check out your link.

I feel like the valve must be sealed to the tube. If so I bet disco o rings would work for that.

I’m probably wrong. Haha.

I over paid for this one on eBay recently but wanted it bad enough to do so. I had one 8 years ago and ended up selling it off. I think that the person before me hacked that one up if I remember correctly.

I know a guy who had one up for sale a while back if you want me to put you in contact?

What I did on a crosman 700 when I needed that flat amber colored seal was took apart a few crosman co2 pistols until I found one close enough.
Another thought is they make adaptors with a check valve so you could simply unscrew without loosing all air. The adapter will have a seal that might work too.

Contact Rick @ Precision Pellet and ask him to put a re-seal kit together for you.

I will try and find that adapter. Is it something that screws to the 88 gram?
