Hello all,

Well I was on www.bcvids.com/store last night, and was looking at his Schrader Valve. I saw that it is only rated to 160 psi, but I want to shoot my gun at maybe 180-200 psi. What kind of fill valve should I get so I can do that, or can a Schrader valve take up to 200 psi pressure??

Soo if I need to use another type of fill valve please let me know...Thanks


And how do I mount a pressure gauge into my chamber!! I've been seeing people do it, but can't figure it out..Because my pressure gauge is like a tire gauge, so you have to press the little stick in the middle of it to allow pressure to enter the gauge...

Is there another type of gauge that I should get..And then how do I mount that?

Sorry for that question if it seems stupid..my gauge is just a tire one so I can't figure it out

I use schraders from bicycle tyre inner tubes, they don't normally see more than 50 psi in their typical use but I routinely use them at 400 psi and never had one die on me.

I only know of one alternative, besides the usual schrader.

You could use a ball valve, and a male quick-disconnect.
Open the valve to fill, close the valve and fire.

Although.

I've used schrader valves rated to only 150 psi, and I've taken them to over 200 psi, and that was a rubber one, if you not sure. then get a threaded one, and then wind a nut on the other side, Meaning: Drill the hole, tap the hole, screw the valve in, then on the inside of the chamber, screw a nut on, so, even if it wants to strip the threads and shoot out, it cant.

Hope that helps.

K thanks...And for my mounting a gauge question..Would I need a gauge like this one?- http://www.mcdanielcontrols.com/model.C ... ATEVALUE=T

DOes this type just like screw into the chamber...like no little pin to push to allow pressure through??

Except I would need a cheaper one..That's just an example..it's $100

Yeah, just screws right in. no pins, no nothing, so Drill, tap, screw it in, done!
Dont forget to use teflon tape.

K good thanks a bunch skinner..I'll use your idea with the bolt on the schrader valve thanks a bunch guys..

No worries.

good luck and have fun.

Yes that sounds about right too me, and for the tire vavle, a good one is where it has threads, so it ca be screwd in, then once you ave one of them, drill the right size hole, then screw it in, and of coarse apply some teflon tape or something. Good luck

why would you need a valve that goes to 6000psi get one of those normal pressure gauges that they sell at home depot. there like $7 and i think they go to 180psi. i bought a 3000psi gauge on eBay for $10 once you can check there. and both of the valves i mentioned were 1/4 npt threaded, no push pins just screw them into the chamber and they work

I don't need one that goes to 6000psi..It was just an example for the fitting..

Ive had some problems with one of my valves leaking air (Mainly because problems with my drill loosened up the bit so it spun awkwardly). But reguardless I just put some epoxy where my threads will be going into the pipe and then also on the outside and I never have any problem. I like the idea of using a nut though.

Whats the best way of getting the schrader valve into a piece of copper pipe? The same way with drilling? or do i need to apply anything to the valve so it holds then screw it in somehow?

Is that a threaded one?

If so, then the same way I stated above.
Same deal as PVC pretty much.

Good Luck.

*EDIT*
sorry I forgot, seeing as copper is thinner than PVC, i would suggest applying some sort of sealant on both sides of the schrader, then winding the nut on the inside.

for copper whats the best sealant? i know theres flux or something and then have to use propane torch to solder. I dont know much bout the whole copper construction but wana construct a pneumatic outta copper.
