hey so having had a few co2 guns i know that breech seal wear out anyhoo got my first crosman gun today a 2250 2nd hand so nipped up to my range to chrony 3.5 fpe with 14.4 grain pellet but when firing noticed hell of a draft coming from the base of the breech so i stripped it down as wanted to polish and relube internals when i got to the breech to gas tube seal found a small brass fitting and lots of what looked like perished bits of o ring so my question to the crossgods is were there rubber seals on it if so either where can i get more or should i just replace the whole lot for a ptfe seal ???
thanks in advance
aaron :)
Hello,
Gmac ;)
is that just looks like just an o ring for the top of the fitting to the breech is that all thats needed? if so ill get the o ring set suitable for use with co2 out

It's a flat edged O-ring of sorts. More a slice off a tube really. Again, as Tatsumi mentioned; GMAC is best online but a good dedicated
gunstore will more than likely stock them. "Woody's of Wembley" sells them for example.
It's probably a better deal to order a seal set or at least a few lil' bits to save on postage.
It's the third one from left to right:

EDIT: Is the little gasket present? Only they're not brass so I guess you mean the valve port?
If the former is missing then add that to your order! ;)
