I need to find a way to go from a paintball tank to a npt and have the pressure regulated below 250psi. I would like to stay under $40 if possible. I am not counting the cost of a C02 tank as part of the $40

i found them at menards. The were about $4. hey had 1/4" and 1/8". They were in plumbing near well pumps. They came with a metal screw on cap with an o ring in the cap. It apears to be made of nickle plated brass. It was made by a company called water source.

Or just buy one with 1/8" NPT threads and step it up with a bushing.

I am open to that idea
Do you know where i can get one of those?

Does anyone know where i can get a schrader valve that will screw into a 1/4" NPT? Home Depot doesn't carry it.
