i must have been around too much solvents when i put the fill nipple in. i stupidly put in one of those quick disconnect 1/4" fittings for air tools which doesnt keep air in the tank, so i have to fire it with the compressor attatched. is there a 1/4NPT fitting that does have that feature?

You could put a ball valve between the air compressor quick connect fitting and the cannon's air chamber.
It's hard to soar with eagles when you're working with turkeys.
Hydraulic quick connects seal on both sides (as long as you're *very* careful with them), but they don't fit normal quick connects, and the male and female cost about $30 together. Other than that, just use a ball valve between the male QD and the chamber.

Remove the male fitting and replace it with a sealing female.cooptroop123 wrote: i stupidly put in one of those quick disconnect 1/4" fittings for air tools which doesnt keep air in the tank, so i have to fire it with the compressor attatched. is there a 1/4NPT fitting that does have that feature?
Get a short length of pressure hose and two barbed males. Make a male-male adaptor for you compressors hose.
Pressurize the gun then remove the gun-end male connector on your adaptor.
Careful, if you fill via the pilot volume htere may be enough leakage when you disconnect to fire the valve.

Some guy sells them on www.trademe.co.nz as Topmaq brand, they look exactly like that. And yeah just occured to me, they do say NPT actually.dewey-1 wrote:Are you sure that you matching threads?

I know in the past you have stated using American NPT on other threads.
Has anyone in the US also encountered that problem?
But I don't think that's the problem, i've emailed the guy about it, waiting for a reply. I could actually squeeze the threads (once broken off) with pliers and they just crumble like nothing.
Over-tightened, maybe, I do it every now and then with 1/4" threads, but after the first time I did it with the reg, second time round I was actually un-tightening it when it just broke.
