Umarex Umarex fill valves

[Vortecsix]

I have two leaking airguns an umarex g30 gauntlet, and a javelin pro I purchased here awhile back.

both have bad fill valves, I tried to order some 1/8 npt an some ban threads. I finally looked with my tap and die at and best guess is they are M10 x 1.0 threads.
I see many on the market but non seeem to have the neopreen seal at the base like the factory ones.

anybody have some insight as to where I can find some replacements that have similar seals and proper thread to install in factory bottles? Thank you!

I considered a flex regulator for the gauntlet, but looks like I need to swap bottles too. More than I want to for a hog gun…. Any insight is most appreciated!

Not familiar with the umarex valves in particular but you should be able to open them up and fix them rather than a complete replacement. Probably just an oring.

I should add one on the javelin pro leaks around the threads on the outside, and the g30 leaks from the middle of the brass filter. I just want to s so with serviceable valves so it won’t be an issue moving forward.

One of the *spares* of which I keep several of each type. M10, NPT, BSP and M8. I ordered 5 of each from AliExpress.

Amazon has the M10 fill nipples

I notice the ones on Amazon don’t show the outer o ring, wasn’t sure if that would be an issue or if ptfe tape would be ok Amazon shows the outer ring on the m8, but not the 10.

i had ordered the npt and bsp, but quickly realized the thread was wrong. I considered keeping them, but my other guns all have probes, so I figured id not use them.

Does anybody use the ptfe tape for installing their fill valves ?

Kind of funny. i came across this thread in a google search. Same as OP stated, i have a Gauntlet G30 and Javelin Pro both leacking through the fill valve. OP did you come up with a solution? And possibly a link where to purchase? i dont want to go through Umarex. Thanks in advance!

I tried BSP, NPT, M10, and M8, none were right. I replaced an o ring on the inside and stopped that leak, but the outer oring was brittle, and my replacement quickly failed. I just ordered a new 3100 regulator and fixed one…. I still have to hobble a fix for the the javelin, I’d like to try it for gator season!
