O-ring size for TM G17 magazine

[StayOnTarget]

Hey my Airsoft brothers I'm trying to find the correct size o-ring as when I try to fill up my pistol mags the gas comes out from around the sides of the fill valve

any help would be most welcome

You sure you’re not hearing the air come out of the mag as you fill it?

It’s mean to on a TM, equalises the air pressure, once the mag is full, you’ll actually see the condensation from the gas rather than just hearing the air

So unlike say a WE mag which just stops on being full a TM will vent out from around the sides of the fill valve? The mag does hold the gas but it dosnt seem to cycle the slide very well is that due to the wrong gas (nuprol green)? Even so I'd still like to know the o-ring size even just for future reference 

Thank you for replying mate?
