valve setup in Hybrid?

Squeaks;I wrote saying sch80 not sch40.

And Pete Zaria,I believe Rambo has made a piston hybrid cannon.Even if it is a 'mini' it still counts .

SCH 40 should not be used in a hybrid, its not safe, pressure rating means nothing, there is alot more things involved.

use a sprinkler valve......not modded
