how much PSI do u guys normally use in your guns? i'm just using normal sch40 Pvc ...with a pvc ball valve...nothin fancy at alll works awesome though. At 80 psi it'll lauch just over 200 yards. I was just wondering how much more i could put in it though. I really dont understand why you put all these fancy valves in your guns... buy the 12 dollar pvc ball valve it works perfect



thanks

Try a sprinkler valve and you'll understand.

Depending on the pressure rating of your ball valve I would say that up to +/- 120psi is safe but some people go a lot higher.

I dont like ball valves because when you pull it your gun moves.

look at the pressure rating of the pipe. devide that in half if you have any threaded fittings then subtract 10% off that and you have your max

um....i just went and read my pipe.... it doesn't say the pressure rating....i dont have any threaded parts....all of my connections were smooth and i glued them in

You did use pressure rated pipe, right?

i guess i didn't ....i figured all PVC pipe is the same i asked the guy to cut me some PVC pipe at the store and he did

Well good thing you found out early, and definitly do not use that pipe in your pneumatic for saftey reasons.

well it works fine right now....i just wont go over 85 psi

how long is the pipe ? it could be short enough that the pressure rating was cut off and is not showing

nope i went and looked on the peice i cut off of no pressure rating at all....but i havn't had any problems yet

I have a friend who used non-pressure rated pipe and luckily it didn't blow up, but its only a matter of time, especially with the higher pressures associated with pneumatics. And if it does blow up, expect lots of shrapnel because pvc doesn't crack or sheer, it shatters.

ok....but that will only happen like if i go more than what i have been using right? if i keep it under 85 psi it wont blow up will it?

You're not safe at 85psi, I wouldn't put more then 20psi in non-pressure rated pipe. It could explode at any pressure.

are you serious?!?!?! what is the difference between the 2?? i mean i look at the pipe i dont see any way it could burst it's pretty thick...
