Pressure Rated PVC

[octane89]

I know what it is and how to see if it is or not, but on pvc thats says Nsf-pw, what is their pressure rating? On pipe it's obvious since it's listed right there already. I have a 3" tee and am working on a 300+ cubic in pneumatic and I want to use the highest pressure I can. The rule of thumb is don't go over the weakest parts rating, but I don't know what some parts are rated too.

If you need to know what parts I may be using, it's mostly tee's and elbows (in 2").

I wouldnt use pvc for pressure over 300 even though some of it may say 300 psi or more. I would just go with copper or other metals.

Yeah, or just go with SCH80 or SCH120 to be on the safe side.

Pressure rated fittings hold as much as the same size pipe. (The exception to this is threaded fittings, which will usually hold less pressure before leaking)

ummm guys i think he is saying hes gonna build a 300+ cubic inch chamber. not a 300psi cannon.

as for the rating on fittings, BC is correct. ^^

Ok thanks for the info. And cwazy1 is right on the 300 cubic in part, but Im still gonna try to go as high as I can in psi.
