Are these good for Pnuematics?

Unread postAuthor: -T0OL- » Wed Oct 11, 2006 9:04 pm

1. PVC RIGID CONDUIT - CSA Its a grey color.(no pressure rating that i could see so im gunna guess no)

2. ABS/DWV it says schedule 40 on the pipe which is the same as some PVC piping is it not?

if either or both are no good dont tell me that they will blow my face off... just say no.

1. No i dont belive that will work.

2. DWV, nope look for pipe that says NSF-PW on it.

For pnuematics you are going to need pressure rated pipe prefferably SCH 80 unless your gonna keep it at 30 psi but thats no fun.

Not if it has DWV then again DWV doesnt matter all the time what you need is pipe that has NFS-PW on it that means its pressure rated.

I have thought about using the rigid conduit stuff for a barrel on a paintball pneumatic... but I would not use it for pressure.

As for the ABS just dont buy it; some people say its ok to use in combustions, and EVERYONE knows that its bad to use in pneumatics.

If you can find the pressure-rated ABS at a reasonable price, then you are one lucky person

Don't look for [NSF-PW] Look for a pressure rating. Pressure rated pvc comes in DWV too.

"Don't look for [NSF-PW] Look for a pressure rating. Pressure rated pvc comes in DWV too." ~frankrede

Bah! How many times has this been addressed? 'Pressure rated' [NSF-PW] PVC will most often have a 'DWV' rating also stamped onto the point. This means you can use it in both 'under pressure' systems, and also in gravity, next-to-no pressure systems. The 'DWV' doesnt automatically make it unsuitable for pressure use. For a sh*tty comparison - A Hummer says its both able to go offroad [NSF-PW], and do road driving [DWV]. Why would one conclude that it could only do road driving [DWV]?

"Sch 40 is usually good up to 150 psi!" ~benstern


I love how you pull 150 PSI out of your ass like its some kind of magical number in which the pipe is no longer safe.

<a href="http://harvelplastics.com/pipepvc-sch40-80-dim.asp">HERE</a> is a rough idea on the common pressures according to dimensions the manufactuers suggests there pipe to be charged to.
