Help getting replacement fill valve

Mr. Tezza

Hey all,

I'm hoping that somebody on here may be able to help me as I have been onto a few different places and no joy.

I am looking for some replacement fill valves for my pistol magazines, they are magazines for a PRE system 7 KSC USP.45 (fullsize not compact). Looking for 4 in total.

Anybody help?

Did you take them apart and check the spring is not compressed and the tiny tiny o ring inside the assymbly is seated correctly?

Most of the fill valves use the same sized tiny o rings inside them so if your find problems locating the correct fill valves buy cheaper easy to find valves and recondition your original valves yourself. It will only take 5 mins to do the 4 valves.

Mr. Tezza

I checked the o rings and they seem ok, I think it's a problem with the valves themselves so was gonna replace them.

Did you stretch the little springs?

Mr. Tezza

Little springs? where?

thermo

Inside the valve body.

If o ring "A" is ok and seated properly but still leaking put it in some brake fluid for 24 hours this should swell it up and make for a better seal.
Stretch spring "B", put it back together and see if its still leaking.

Thanks for the info but I can't open the valve body up to reveal the inner spring and o ring, are they press fitted together? don't want to break them!

Usually they are a screw together job sometimes they are tight though.

Thanks for the help, opened up one of them, re-seated the inner o-ring but the outer one didn't look too good so ordered some o-rings and gonna replace them on all my pistol mags just to be sure,
