pvc vs steel questions

Unread postAuthor: airsofter135 » Mon Jun 23, 2008 11:16 pm

Im building a pvc cannon, using a tank for compressed air with a pressure regulator. how would you connect your regulator to the rest of the cannon? galvanized steel parts or just pvc. Steel obviosly has a higher pressure rating but can one connect steel to a mod sprinkler valve. i guess the question is, how would one go about connecting the regulator with pvc or can i just connect galvanized steel with the valve directly? sorry for stupid questions!

Your cannon will only be as good as the weakest part/piece.
So as long as you're using pressure rated pvc, steel or pvc won't matter.

Several launchers in the showcase combine metal and pvc.

Something like this new addition? :roll:

BTW be sure to use teflon tape on the metal threads.

If the pieces have the same threads, you could always thread them together. :wink:
