Like CS has posted only way you will get a air tight seal able to handle compression is going to be with tools. I use 3 wrap arounds of white PTFE tape then crank it as tight as possibly prefect seal no leaks. Even if you coat them in jb weld or epoxy which I would not recommend it won't have enoug...

If teflon tape and elbow grease does not work, try some epoxy or j b weld when you thread it together..............

Nice build evan... very cool design.. looking to see some ggdt results. I cant see it opening faster than a dust collector valve... Awesome though...Love the design.....

Very impressive.....I want one!!!

Block that eq. Hole, you dont need it. Next wrap that piston with one layer of electrical tape around piston. Now get rid of that clear hose and hook up the blowgun direct..
