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.

15mm for perfect paintballs. with my gun i only need 20psi to fire 80m fairly accuratly (using a modded 'phram valve).

i used 3/4cpvc on my gun, it works great, put a hole through 2mm thick platic. if u want u can see my gun in the submit pnematic section. i think another good pipe is 3/4 sch80, not sure on that though

paintballs r supposed to be .68 inches but they vary if they have set for a while and some just vary but they only vary like .002 or like .003 of an inch

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

[iamthewalrus]

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

the grey sch 80 3/4 inch sprinkler risers fit the balls perfectly with no wadding of any kind
