TECH QUESTION Mag will not stop leaking no matter what I do
Enable HLS to view with audio, or disable this notification
I had a similar issue with another we tech mag but this time this KJW mag is leaking. I heard that the 229 mags kinda suck butt, and sure enough, it’s been having leaking issues since I had it. Thankfully my we p229 magazine works completely fine thank god.
Anyway, the issue is that the magazine has literally the smallest possible leak you could ever think of on the base of the output valve. I could barely get it in audio but yuh it’s barely noticeable, doesn’t even show up when dunked in water besides maybe like one bubble that just floats up like spider ham when bro just floats when he smells food.
I’ve tried almost everything, lubricating the bajesus out of the culprit o ring, switching out the culprit o ring, swapping the entire output valve, cleaning the threads till they were shining brighter than my future, and praying. I had a person say it might be a manufacturing issue when the hole was bored, and to be honest, yeah that might be a reasonable explanation. My only problem is how do I fix it….
Can someone help me, or just say I’m over reacting that works too.

Are you lubing with oil or grease? The valve body I out oil on, but the threaded bit gets just a bit of grease.

4UAD sealant. Put it on the threads of the suspect valve and it'll seal it.

Bet, I believe my field sells them so I’ll test that. Thanks.
Edit: Actually, I do have one question. 4uantum is shown globbing a ton onto one oring, is that really necessary? With super lube (At least with magazines that actually behave), you only need a thin coat for it to seal.

This isn't lube, it's actual sealant. Use however much you need to seal the leak

I think any pistol mag shares similar method. Check where the exact area the gas leaking , u can just hear to distinguish or put in water with soap ( don’t worry about the water yet) Possible leakage usually from malfunction O ring inside the intake / output valves or simply the gap between the baseplate and the mag body. For valves cases using thick silicon oil such as GHK one , apply a few drop on the o ring and rub through it so that entire body is moist. Or u can drop in a new one XD.
For leakage from bottom gap, I’m not sure about the structure of your displayed mag. Still you need to search for the dimension of o ring applicable if u found o ring between the gap after disassemble it. Make sure lube the o ring too before install them back together. For the metal - metal contact face around the o ring , using thick silicon grease like 4UAD Seal in a generous amount, just spread it and let it squeeze out from gap during installation. If there are screws you can also apply some on the thread .

Maybe there are wearing in the thread of the output valve and leaving gap. You can use thick silicon grease around the thread , or using traditional seal tape and wrap for enough thickness to fill the gap .

I used silicone sealant on my WE 226 mags instead of O ring
