Does anyone have a link for heat resistant o-rings to seal 209 primer pockets on break open CVAs? I found an old 2016 post with a link but I don't know if there is another better option in 2023. Those o-rings were rated at 250 deg F.
This is the link to the correct oring. 9262k611Does anyone have a link for heat resistant o-rings to seal 209 primer pockets on break open CVAs? I found an old 2016 post with a link but I don't know if there is another better option in 2023. Those o-rings were rated at 250 deg F.
The oring itself is still round, it has a square cross section. It would make more surface contact at the sides and bottom of the primer pocket and against the face of the primer. The round ones last 20-40 shots before the are wornout and i replace them. Im just thinking they might get 50-60 shots instead. Just an experiment.

Thats what i hope to find out with the square profile o-rings. If they last longer or seal better than the round ones. I may try some hot loads and might get to try them with smokeless.Using the W209 Winchester primers my Optima pistol and Accura V2 shoot clean without the rings, so those are the only primers I use in those guns. My Kodiak .45 needs a ring for any primer.
I'm curious how tough the rings are should my Patriot need one using smokeless powder? I get about 20-25 shots out of a ring in the Kodiak with a moderate powder charge. The Woodman is also a .45 but will only see smokeless powder.
Don’t forget that the oring will need to compress to .010 or less and the round tube style would do it much easier. I’m just thinking you’ll probably have to slam the action pretty hard to get it to work.I was thinking about trying these…

Same buna-n but in a square profile, just to see if they last any longer.

So ive been tinkering with some breech plugs and the square profile o-rings. Thanks billyboy*, for sending me some. In my CVAs the sq o-rings compress just fine. In my Omega… not ‘no’ but HELL NO! So I did a bit of mod work to a few breech plugs that I’ll start a new thread on, soon.I Like the idea of more surface area. Curious if they would be Harder to Compress?
