CMBecker Gas Ball Lock Leaks

[Jose_in_HTX]

Hello,

I am a bit paranoid about CO2 leaks so I tested two new gas ball locks (grey, CMBecker) that I recently bought. Both, to some extent, seem to leak a small amount of CO2 (from the top) when the lock is placed under water. (see linked video.) Is this to be expected? I certainly thought it was a problem with the first, but seeing it on both makes me wonder. Have any of you see this problem?

No, that's not normal. I would suspect the internal gasket.

Definitely, the leak is around the threaded cap. It's likely just a tad under torqued...

Cheers!

I should have added that I change out the stock gaskets and replace with #013 O-rings. You can feel them engage when they are being compressed.

Interesting. I have at least 32 cmb qds in constant service in their oem state. Never thought there was a need to mod them...

Cheers!

So just to make sure I understand. In the image below, my leak appears to be coming from the area depicted by the red arrow. That little circular part between the body and the "thing" that maybe can be tightened. Are you saying I can stick a screw driver in the area shown by the black arrow and tighten this down? Apologies for such a newbie question. This is all very new to me.

Yes, that's what he's saying. You can also remove that top completely, to disassemble everything for cleaning and sanitizing.

Awesome! I will certainly try that. Thanks for the hint. I was wondering what the notch was for. Seemed a bit wide for a screwdriver, but I will see what happens.
