It doesn't matter what material you are making a pressurized cannon out of or how that material it is rated, you cannot pressurize homemade actuators or components. During the time the rod it traveling in the cylinder, it is a pressurized piston actuator. The rules are explicit that only rated, unmodified COTS pneumatic components may see pressure in the system.
