Toilet paper test
Does this mean I have a leak where the gold washer (breech/valve) is?

Notice: Half the O-ring was sucked in.
Whom ever said that the .25 pushes so much air and will eventually spit out the o-ring is correct.
Sound with the o-ring in:

I then replaced the o-ring with the OEM washer. I applied a little of elmer’s glue to keep the washer in place so that I could align it better.
results: It blew the toilet paper off

I guess I have to contact Tony for a replacement piece.
I´m willing to bet it´s no custom – just a common millimeter ring. Give me the dimensions (OD,ID and thickness) and i´ll grab a pocketfull of Cu-rings with me from the work. Won´t get blown thru the hole and will seal far better than a Brass ring. Why, in the name of hell, use Brass for sealing that part ? Beats me …

Of course not, thus i suggested the use of Cu instead. Rubber was said to be too soft/pliable. Sorry for the brutal, uncalled for attack – i was thinking about Cu all the time. My bad …
Brass won´t indeed compress, not before the aluminium seat will anyway.
I went to two hardware stores and none of them carried this so called common crush washer that Ville said. I PM Wingman and he said it was a custom piece. Since I was at the hardware store already, I picked up an oring of the same size as the washer. The first few shots sounded awesome, but as I shot more I notice it got louder. When I opened the gun back up, it looked like a fat lady breathing in a donut.

Please sober up and read again! Brass is not the same as copper…
Dr.:evil:
If I understand it correctly the oring doesn’t blow out but rather creep in and goes out the barrel so why not try a thinner ring same size as or slightly thicker than the brass ring so it don’t get pushed in to the transfer port. In the steel singelshot breech there is a slight rim that keep the ring in place inwards don’t know how it’s done on the later and bigger models. Anybody tried a stiffer oring or maybe different materials like EPDM or PU or…?

Are you drunk ?? A Cu ring won´t compress ?? Come on … Of course it will – once. And almost as well once again if you “glow” it.
What ?? EdGun “original” or one from a Hardware Store ?? Those cost maybe 50 cents a piece over here.
The best thing to do is to order a new one – or a bunch of them – from the nearest Plumbing Store – since those are probably standard sized crushers and cost virtually nothing. The heat-trick works once nevertheless.
It’s costs me 15 dollars each, yikes!!!

If it’s a brass ring it won’t compress. The only thing that’s gonna seal it is perfect alignment and of course adequate pressure/tourqe. You can tighten it as much as you like and the only thing that will happen is the alu pieces and then ring will get deformed and a seal more and more difficult. I still think an oring of the right size and the two pieces it shall seal correctly machined to give the oring support.

If it is indeed a Cu crush washer you can do this : Heat it up , with a Torch of course – a lighter won´t do it – without melting it but to the point it glows. Let it cool down and then install. An old trick for leaking Cu crushers.

Do you think a harder o ring or maybe a delrin/nylon washer would be better suited than a brass ring with nothing but torque pressure from the breech screws would work better? How much torque is needed? Also given the tendency for the screws to get too tight and strip out the heads it would seem that brass ring eventually leads to more issues. Of course I know very little about the Edgun.

Thanks Gabe, about to take the gun apart now to check the alignment.
You may also have been experiencing velocity fluctuations. Did you notice any? Anyways, try the above. Hopefully, that will fix the issues.

Looks like it. That may also be the cause of why your gun is loud. The washer is suppose to “crush” between the breech and air exhaust port on the valve body. Make sure the parts are aligned before you tighten down the breech screws.

Ville, this is what WingmanNZ posted on another thread:
Any one got the brass washer in their .22 R3s?
