how much psi will dwv fittings hold on a pnuematic. i could only find dwv couplings and an end cap and dint know how high i could take it to?

dwv can hold over 100, but stay in the 50-80 psi area.

well i worried that the end cap will either explode or shoot off. will the couplings matter because all the are doing is hold the bushings on to the pipe?

i doubt that the couplings will matter.

does anyone actually know how high the fittings can go to. Would it be safe to use a pressure rated cap in DWV fittings at 100 psi?

I wouldnt personaly,because i have had these blow off on combustion and they are said to produce around 30-50 psi peach preasure,so jus keep it down a little lower or use pressure rated items.
