Hello,
I'm in the process of buying materials for my pneumatic, but I'm confused about the process I need to undergo in order to install a metal schrader valve, like one of these.
I was planning on drilling a hole in a plug like one of these (except in a larger size, one inch to be precise), sticking the valve in, and then using pvc primer to secure it. I'm planning to bring this gun up to no more than 100 psi. Also, I'm confused on how to install a pressure gauge. I swear that some time ago, i saw one that was inline with 1" threads, but that seems to have disappeared now. If anyone could hhelp me, it would be greatly appreciated.
Thanks.[/code]

That threaded endcap seems unnecessary, unless you intend to switch the schrader and gauge from gun to gun. Drill a hole slightly smaller than the schrader or gauge into overlapping PVC (2 layers), and try to screw the threaded side in. If the hole is too small, make it bigger. Common sense. PVC primer primes PVC to be "melted" together with PVC glue. It will not secure anything.
If what you are trying to put in has no threads, use marine epoxy like you would use glue.

Sorry, I meant pvc cement. But if I screw it into the plug (follow my previous links) do I still need marine epoxy/pvc cement? If so, which will work better? The plug wall that I'm going to screw it into is about 1/4 inches thick.Hailfire753 wrote:PVC primer primes PVC to be "melted" together with PVC glue. It will not secure anything.
I would defiantly get reducing bushings and put it in like that. Your way will work.

Don't use PVC cement for attaching a schrader valve. PVC cement should only be used to join PVC to PVC, not PVC to metal.
It's hard to soar with eagles when you're working with turkeys.
I know you have a metal one and i know that this is not an appropriate way of attaching one, but i have a shcrader valve that is just super glued in that i have taken to 280 psi. I would recommend epoxy putty. it is easy to work with and is strong.

Drill a hole, put the schrader valve into the drill's chuck, and drive it in there. The metal threads on the valve will cut into the pvc. You should give it a couple wraps of teflon tape for good measure.
If you really want, you can also add some epoxy...I don't see the point in it, though.

Use one of these. It cuts threads perfectly, the grooves remove the threads cut material as it cuts the threads deeper.

Drill a hole trough the pvc (preferablle two layers, where a fitting connects with the pipe) and tap it in.
The metal threads on the gauge are strong enough to tap trough the pvc, but using a real tap for tapping threads would be better.
You can use epoxy to seal it when it leaks, or just use it anyway to be sure.
