try McMaster for the valve, I've also heard some Walmarts have them with the auto parts, but I've never seen them in stores. what i do is i epoxy the schraeder from a bike inner tube into a brass 1/8 x 1/4 bushing and use that. and sorry, i dont know much about copper.

If you want to give me some money I will run to the local plumbing shop and get one and then mail it to you.

Do what meatballs did. Strip the rubber of a used shrader and epoxy it into brass bushing. With that setup and the copper you could hold probaly around 300-450 psi. But qev's can't hold that pressure you will have to use a brass ball valve or build a piston valve in a tee.

Go to ace hardware and look in the pneumatic fittings section.

Well then that Ace sucks. You can however order the parts on acehardware.com and ship them to store for free.

Thanks for the informations, i'll use a used schrader valve.
And i don't think i will put more than 100 psi in my gun so i'm safe with that.
