how well does non-pressure rated sch 40 pvc do?

[imjustpk]

im wondering if non pressure rated coextruded pvc is alright in pressure capabilities. i imagine it to be better than abs, but does anyone know about how well it can preform, and how much pressure does an average size combust cannon make?

40psi. It should be fine on a basic combustion if its thicker then DWV. But do not use it on a pneumatic

thanx man, do u know how much psi a reg combust might make, would using propane or butane be too much?

[MrCrowley]

A basic combustion with hairspray your looking at 30-40psi. Thats why I put 40psi in my first post
A propane cannon with perfect fuel air ratio will spike at about 80-100psi.

Was it the underlining? I just underlined them to make sure people read correctly and carefully.
