SCH 80 conduit?

Unread postAuthor: judgment_arms » Sun Oct 22, 2006 8:23 pm

I was at Home Depot earlier and I saw SCH 80 PVC, but it said something about conduit and radio something. It had a flared end like conduit. Will this SCH 80 for pressure?
Also in your opinion how small could you make a “tee” piston valve? Would 3/4” be doable? I’m trying to make small rifle sized cannons, so any advice on doing that would be nice to.
Thanks all.

Conduit is usually used in electrical applications and is not pressure rated unless otherwise stated on the pipe. If it is not pressure rated I would not recommened using it for a pneumatic, however you should be fine if you use it for a combustion.

And Not cellular core, the conduit is much more brittle ans is likley to snap or go pop. I would reccomend that you only use pressure rated pipe on all parts of a pnumatic and posibly ABS on a combustion.
