Why would you want to disconnect a quick connect (or any fitting for that matter) at such a high pressure?

Anyway, most remote lines that can be purchased at paintball stores come with quick connects. They are usually 1/8"NPT. I'm sure if they come on remote lines, they can be purchased separately. As far as converting the ASA threads to NPT, I'm unsure. Maybe some form of epoxy would be in order.

As far as quick connects go, look at your local auto parts supplier. They should have hydraulic quick connects in a variety of sizes from 1/4" to 1"( :shock: ), that are rated for at least 3000 psi. About 30 bucks for male + female. They also have all sorts of other interesting hydraulic stuff (like flexible hose rated for 5800 psi).

You could obtain a greater degree of safety than air with an inert gas, such as pure nitrogen or helium. Even small towns usually have some sort of a compressed gas depot, which is, IMHO, a spudder's paradise. You could easily buy a backpack sized, 2500 psi nitrogen tank for under $150, then you just need a good reg (50-500 psi regs can often be found on eBay for under $80), and some of the aforementioned hydraulic hose and quick connects, and you will have a relatively cheap high pressure setup (unless you choose to buy a 93 cubic foot tank like I did.)

For high pressure setups, please don't epoxy incompatible threads together (sorry Jack). Just spend a few extra $ and do it properly. I don't understand the trend toward using repurposed paintball equipment. It vastly complicates things, and it can be really expensive.
