AEA AEA O-Ring sizes

[uladz]

Anyone has complete list of all O-rings for AEA guns? I have one HP Max .35 and another Challenger Pro .22 leaking. So, it seems it's kind of a norm for AEA to start leaking at some random point of time. I know Fox Air Power sells O-ring kits for each model at 42 bucks a set. But I want to just buy all sizes in bulk to have them at my disposal whenever I need them the next time yet another AEA starts leaking. If anyone has O-ring reference sheet, please share. Thanks guys!

I spent some time shooting a 357 max and (later) a .25 carbine, had my share of leaks, but none of them involved o-rings, so that is something to keep in the back of your mind as you try to pin the leak down.

They’re very minimal o rings in there. Valve stems will probably be your biggest issue

What was the leak source in your case? Can you advise on the best practice to find the source of a leak in AEA rifles? The HP Max has a very slow leak that I have no idea where to start to look for it. The Challenger one just dumped all the air in 5 mins one day and I have a feeling that it's due to failed gauge or something similar. Thank you for sharing your experience!

Yep, I've seen people recommend replacing the valve stem with "enhanced" one that can be bought from eBay like this https://www.ebay.com/itm/256523570804. That one supposedly fixes this issue.

Hey brother mine dumped the air from the valve fast you can hear it from the barrel. Slow leaks are usually gauges, fill ports…… plumbers blue leak detector works well you’ll find it quick

 

[MrP]

One place where a slow leak can happen is at the check valve at the fill port. This is the little one-way valve that allows air to be pumped in. It can be tightened from inside the air tank. Another possibility is where the air gauge screws in… Mine was maybe early model but there was a pretty delicate arrangement with a nylon washer and o-ring that tended to get out of whack. My valve seats kept cracking but that was a relatively quick loss of air out the barrel

Then wipe down with some balistol and a rag

Yep, balistol is the way to go. Will try it out!

Sometimes I use a small kids paintbrush to apply if you don’t want to drench the gun sometimes I partial dunk the gun too.
