hey guys I'm looking for a pressure rated fitting similar to this http://www.milmar.com/images/Sch%2040%2 ... 28S%29.JPG
but 3" in diameter do you think you guys could help me out.

p.s. The kind I'm looking for fits inside fittings not the pvc itself, its the kind where you need a coupling to attach it to pipe.

Any particular reason you must have one of that style? Correct me if I'm wrong, but usually, curved surfaces can withstand higher pressures...

one word my friend "piston". I am making a new piston for my 3" porting cannon and i need one of those to use as the backing for the sealing face.

I have already contacted my local plumbing supply and they don't have any that are pressure rated, so i have decided to order offline, if i have to i may end up using a dwv plug but i would feel better if it was pressure rated.
