Ok new problem: I can't use quick connections on this, after 150 psi it's practically impossible to connect any thing o.o

put a ball valve on your gun and and one to let air out from your hose, just make sure your sure gun is closed off. but i would get high pressure quick connects if your going passed 300psi.

A bleed valve of some sort is a good idea anyway, even high pressure quick disconnects aren't designed to be disconnected under pressure.

Does your compressor have an over current or overheat protection ?

Ah, ok, one sec, lemme try to find a video I saw...

Found it. Skip ahead to about 3:36, he has a regulator with a valve he made, check out the valve and see if it would work. (I suggest you watch through from 3:36 for a full description of how it works...)

not that i know of, its never on long enough to get hot, takes about 40seconds to fill 1l fire extinguisher to 400psi and then i go to shoot, that tank last 20 shots, in that time it cools off.

i riged a safety pop off valve at 450 but when it pops it hits the off switch aswell so it turns its self off :lol:

Ok, was just wondering if the higher pressures achieved with your compressor were due to not having the current limiter. Mine won't make it past 1000psi even with a second compressor feeding air to it, the cut off switch always stops it. I'd be interested to test a compressor without the cut off switch to see what happens, but I don't really want to sacrifice one of my two good compressors, I'll have to try and find some more.

Wyz, I am using a clear plastic tube found near the brass fittings at home depot for my sprinkler valve pilot, and it works perfectly. You would need a hose barb to thread, then a coupling and then the industrial connection to make it be a quick connect.

push to connect hose and fittings, that stuff is the bomb. http://cgi.ebay.com/TEN-Push-Connect-Ai ... 483d80ab18

you have to find hose with the pressure rating you need. i have some rated at 2500psi. im sure poland_spud will come soon and give you links galore.

Wyz, it holds one hell of alot... Not sure yet, dont have a compressor to test it, but it holds 40 psi easy... I think it holds 120, but I'm not sure...
