Western Airguns All Things Western Rattler 357 & 45 - Master Thread

[Airgun-hobbyist]

@Airgun-hobbyist Okay, so I looked again and what I noticed is there’s two places where an o ring could fit. I drew this diagram to help. It’s a cross section and the red is where there’s currently an o ring which is like f’ckin impossible to get to(I have some nice channellock picks and it’s still impossible). But there’s a space that I marked in blue between the threads and then ‘shelf’ which looks like it could hold an o ring but I’m not sure it should.

Nvm, finally got it. What a PITA lol. I’ll post measurements momentarily in case anyone else runs into it

It's good to see that you got it out of there. For future reference, because metal picks are a potential failure point of scratching the sealing surface, try a blast of high pressure air from an air chuck nozzle to get the edge of the ring partially out of the groove.

Thanks for the advice, so unfortunately after replacing the o ring with one from the AoA repair kit it still had a leak : (

Reached out to AoA and Shane confirmed the appropriate size is 12mm OD and 9mm ID of buna n 90 and is sending some more. I waded through some o rings at the machine shop and we had HNBR, viton and buna n 70 although they’re all in imperial, but they did have a metric 9x12 that seems to be slightly oversized so I think I’ll try that next with a tiny bit of silicone oil.

I’m assuming having slightly more rubber is better than less.

In regards to the Western barrels, Rob at AOA had this to say on 12/05/24

It looks like the oring-to-valve seal is leaking, not missing. You need to degass the bottle and then remove the valve and replace the o-rings.

I wonder it that bottle would thread up to my sidewinder..?
