Maybe if you would look in the other section of this site, then go to pipe info. It took me 10 seconds. 3/4" sch 120 is rated to 770 psi. But it's not very likely at all that you would be able to find it.

Walrus, if sch 120 fits pbs, then sch 80 would be a little too big.

sch120 fits better, but i think sch80 still fits better then 3/4cpvc, and since sch120 is like impossible to find sch80 is a good replacment
