Nice to know they are now available for HPA.... a link to your source would be helpful....Bob
Unless I misunderstand that Ad.... that slide check is intended for a Paintball marker, which would be fed from a regulator set to roughly CO2 pressures.... and certainly protected with a 1.8K burst disc on the output side.... as you would always use on a Paintball gun.... The "system" pressure is 3000 or 4500 psi.... but the working pressure would normally be about 850 psi.... JMO, and if you are using one at 3000 psi, I'm glad it's working for you....Bob
I think most slide-checks are "self-bleeding", at least the ones I had were.... That was the problem, when the vent hole slid past the O-ring it blew out at much over about 1100 psi.... I gave up on them for that reason.... I had a coil-hose blow at 3000 psi, even though it was rated at that (stamped right on the side)

I also use a "tiny" tank so that I don't waste air when testing.... You can see it in the middle of this photo with the regulator attached....Bob
Make sure the wall thickness of the "tiny tank" is enough for it to withstand 11,000 psi (for a 3000 psi reg.) or 16,000 psi (for a 4,500 psi one)
. So that you have at least a 3.5:1 safety margin....
