Hello all.
Can anyone provide a possible source for a new Co2 o-ring seal for a Crosman .177 cal Mark II Target pistol?
Numrich used to carry them but apparently not any longer. Any help would be greatly appreciated.
Thanks.
 
There are several types of o-ring kits available online. Not speciffically for your aplication, I mean as a universal kit containing several sizes and diameters. most are "china" made, but a few are are good quality such as "viton".

I would research the speciffic o-ring your refer to on the size of it, then fine a small or large kit to get it out of.

Is it just missing , or do you have it to be able to measure it?
 
I can measure it. OD and ID?
I tried matching it at Lowe’s Home Improvement, not even close.
Are the universal kits you speak of for air rifles/pistols?
Thanks for your help.
 
Just looking at the jgairguns site they show several different rings, might help to give him a call.
 
Ok, if it is an O-ring (and not a quad seal, etc) then buy the Metric and SAE set from Harbor Freight. Both should be $15. Every O ring in pretty much every airgun will be in one of the two.

If you want to be sure what you get is correct, go to the Crosman parts catalog for your gun ( probably https://support.crosman.com/hc/en-us/articles/203544200-MARK-II-Owner-s-Manual-EVP-1966-1986- ) and call Crosman and see if they have the exact one you need. If Crosman sells it for $1, you can get it on eBay for $3 or an airgun vendor for $4.

Edit-just noticed the Entire gun parts list is not sold by Crosman any more for that model. Still, get the seal name, etc from the list for when you talk to vendors.

Thanks for the info!
 
Why not deal directly with Crossman? Google them (sorry I don't have their contact info at my fingertips). You can contact them there and they will email you a parts diagram. You have to order by phone but that's not a bad thing because the phone operator is knowledgeable about the parts. Shipping is a flat rate of $4.

I just ordered some parts for a Crossman air rifle and that's how it went down for me.
