Okay, I see what you all are talking about. Thank you. I pressurized the gun to 100 PSI today and shot a T-shirt across the street. Problem is, I am tied to my huge compressor by a 50 ft hose. Any ideas for CO2 portability?

I have already pressurized the chamber to 100 PSI. It held just fine. Just how do you know those are DWV fittings?

Then what do people make Pneumatics out of? SCH 40 PVC? All of those fittings and pipe are schedule 40. This gun has been pressurized to the point that the sprinkler valve failed.

EDIT: Maybe I should mention that the CO2 will be regulated before it is hooked up. 80 Pounds is enough to lob a T ...

notice the paint is unfinished. if testing proves SAFE and reliable then i will finish the paint job.

iPaintball is right, SCH 40 is RATED at 160 Pounds. But it still may burst prematurely if it is handled constantly (IE dropped). However, my gun has been strapped to the workbench for two weeks. I do not believe I will die.

The pressure is printed on the pipe. Plus I only operate the gun at 100 PSI; the valve diaphragm is only rated 130 PSI. Any higher and it will leak open. Making a sort-of "safety" feature. However, there is nothing safe about it. The gun IS unsafe. I only use it to test technologies that will go ...
