When you screw in the QEV, you should be able to hold the fitting in place of the proper direction and tighten the bolt down. I'm not sure how you're having a problem exactly.

Better yet, are you sure it's the QEV leaking? Your threads aren't stripped, are they?

Also, assuming that you still have the o-ring present on the QEV, there should be no need for teflon tape. That o-ring is more than enough to seal that connection point. And I wouldn't use loctite on that fitting unless you never intend to take apart your Ion again and lube the bolt.

If you really have to loosen it to fit it in properly, then I guess teflon would be my next guess. I feel like even with the original banjo fitting, you didn't have to screw it in as one piece. But, if it still leaks minimally, then maybe look in to getting a 360. I've got one and it works wonders.

My only other $0 suggestion would be to dab a single drop of lube on the o-ring. If you had to buy a brand new one because it was missing, then you may want to do that. In my experience, it will cause the o-ring to swell and give a better, if only slight, seal. I do the same thing to my o-ring on my tank. Sometimes it doesn't sit well in the ASA.

So it's one of the Clippard qevs? Brass, square...

I remember the same issue. Used a thicker o-ring (which it came with) to have it seal properly. Has to be a tight o-ring so it doesn't roll up when you screw the qev in. I do not recommend loctite or teflon tape since the added torque to remove it (or screw it in) could snap the threads clean off.

Is it the kind with the quick-disconnect or a barb for the hose? Could be leaking from the hose side.

thats why I dont use teflon its messy. a drop of blue locktight and it seals overnight. But I do have a clippard qev and I know how much of a pain it is to get the threads to line up perfectly with the body. It took me a solid hour, 5 different sized orings and some modding to get mine to sit strait. I havent had to take it off since its an XE

well my threads r lining up fine, and i put a thicker o ring on and teflon tape on the threads and under the o ring and it has a slight, slight leak, you can barely hear it but its still there, and thats good enough for me, before it was leaking in 2 spots and after every game i had to refil my tank, so ill live with this. thanks for the help guys

I know you don't have a 360, but when mine leaked I couldn't figure out what it was until I took it apart and noticed a ton of lub/goop in it. I cleaned it all up and it stopped leaking.

Is it possible to disassemble a clippard QEV? If so, then how?

Ah, alright. Any idea how to get a clippard QEV to stop leaking? My teammates clippard qev is either leaking from the threading or between the square body and cylindrical part.

I put on a brand new oring, but it still slowly leaks. Also, it isn't able to be fully tightened otherwise it's approximately at a 45 degree angle to the body.

Put a drop of blue locktight on it and twist it on. Let it set overnight.

Is the cylindrical part a push-to-connect fitting? You can unscrew that, there should be a tiny o-ring on its threads that's replaceable (if needed).

You can soak the clippard in warm water so the inside gets clean (grease can get inside and gunk it up over time, causing leaks or poor performance).

I don't recommend any thread sealer/adhesive used with a qev since the threads are fragile - trying to unscrew the qev at a later point in time may snap the threads off.

Yeah, it is a push connect for the micro hose. My teammate isn't too bothered by such a small leak, but it's always good to know what could be causing leaks for future reference. Thanks.

Blue locktight is very gentle on any threads, it acts as a liquid sealer that completely covers the threads the first time and wont separate while you screw the item on and it wont get messy like teflon does when you need to remove it from the threads. As long as you don't torque any of those small threads down absolutely nothing should break. Red locktight is a different story.

Although nerdcore doesnt like bluelocktite (you are in your right to not like it off course) I will agree with Shadow. Ive had QEVs on my former Ion Nt and with both the 360 and the virtue I used a tiny drop of blue locktite, hey, i even had to make half a turn more on the threads cause the virtue didnt align well (no issues if you have the proper tools to make that thread).
Blue loctite can take up to 3000psi If Im not mistaken so , the 200 psi inside the marker will be nothing
