Trying to get a Benjamin Sheridan AS392 fixed up.  Leaking CO2 like mad around the neck of the 88g bottle, same with 12g in an adapter.
Looking at the cut away diagrams there should just be an O-ring in a groove there but when I got in there it had a flat disk type seal with a raised edge, looked a bit like the shape of a crown cap from a beer bottle.
Anyone know what the seals down there should really be like?

Welcome to the Crosman forum.
Not sure what size seal you need but try looking at Bagnall and Kirkwood airguns spares as just got there web page up and they do several different seals for your gun.

Or try John Knibbs international as Chambers gun spares are showing out of stock.

I'm sure someone with more exact knowledge than me will be along.

Yours..............dom

Hi Cinimod,

Thanks for the pointers, much appreciated. I did get some seals from B&K off their eBay shop but when i try to fit them they seem to be way too big in terms of diameter. Any thoughts on whether there are different versions of the bottle adapter that are different diameters?

Sorry mate, can't help with any more info really.
You could however try the green forum which is the American Crosman forum to get info on seal sizes possibly..........dom

the early as392's use an o ring bs112 but were replaced by the later flat seal which is like a tap washer
I think the 1077 /umarex flying saucer seal fits them ok

Thanks Ped, that sounds like the screwed up bit of plastic I fished out of the adapter. Guess I'll need to find a supply of the flat seals
