NOW WHAT?

Well, I thought it all was going to work but, appears that I have a mismatch in parts. I can fill my Ninja tank w/o issues. But, when I go to fill my Diana Bandit I get an air leak between the regulator and the long pin control valve. There is a hard washer on top of regulator but does not seal.

Here is Ninja regulator I bought on Amazon: https://tinyurl.com/yxe6bnjg

And here is item description for Long Pin Valve I got from PBMechanix: NINJA PAINTBALL UNIVERSAL ASA w/ LONG PIN for use w/ Ninja Air Rifle Regulator.

Is there another O ring or gasket I am missing?

Check the external o-rings on the top of the regulator. Make sure that they have not hardened or have any nicks in them. Maybe just replace them and try again. These are a common size o-ring; you can find them most anywhere that sells anything paintball related.

Accuracy...

I have looked at the 2 O rings on the bonnet. They are brand new; no nicks, seem to be perfect. When I test with everything hooked up the leak is like there are no O rings at all.

No leak from the small hole in Fill Valve. This is a catastrophic fail. The Reg does not leak anywhere with Fill valve on or off.

I am wondering if these 2 parts are just not made for each other. But, how to tell? The fill valve that I got from PB Mechanix says Ninja | Made in USA and a code of 30-19,

I have message into the PBMechanix blokes.

Thanks

I will check the threaded hole of the fill valve. Beyond the threaded segment, there should be a segment with smooth wall for the O rings to press against. check the inner diameter of this segment with a telescopic bore gauge and compare it with the outer diameter of the O rings ( when installed on the regulator ). If the latter is slightly bigger, say by 0.05 ~ 0.1 mm, then there should be no leak. Otherwise, these parts are not made for each other. 

Those O rings are not the only means for sealing. The alternative is using Loctite thread sealants. I have been using Loctite 565 and 542 in my Yong Heng set up with good results. Standing 4500 psi is absolutely no problem. They are available on Ebay at about $9 per bottle shipped. The drawback is that you will have to heat up the thread by a torch to soften the Loctite when you want to take it apart in the future.

I have that same outfit and no leaks. Mine seems to screw down a bit tighter the reg though for sure.

You may be correct. I don't exactly know if that washer came with kit. I will try w/o and re-post.

Sure would make my life easier if it just works!

Ok. So, new test without the mysterious washer. Fill Valve did screw down to base of bonnet.

Same result. Total fail of O ring to contain air pressure. Nothing coming out of pressure release hole. Quik release AOK. O ring just not seating.

How does your Fill valve look inside? How does the 2nd O ring get seated to something? Mine, there is no way it touches anything that would keep air retained.

I took some measurements:

Bonnet from top to collar below threads 16.84 mm

Bonnet top of O ring to start of threads 5.97mm

Fill Valve Inside to O ring seat 9.8 mm

I am calling Ninja and supplier today to see what's what.
