Shrader Valves

[crazyfreak0075]

Hey guys im gonna build a pnumatic soon and i was noticing that the shrader valve in this topic http://www.spudfiles.com/forums/viewtopic.php?t=3573& is different than the shrader valve sold at www.mcmaster.com.

The one in the topic has a rubber end to it to keep it in and all the one that mcmaster has is a shrader valve with an NPT end to it. Are these too valves different is one safer than the other???

I prefer threaded, but both work fine.

Threaded are the best because if they aren't they will blow out.

Oh they will...

[frankrede]

well I under normal pressures those pop in schraders shouldn't blow out

Hey, I'm just going off personal experiance, not trying to start anything.

Mmmhmm...

I'm using a presta valve cut out of a bicycles inner tube at 200psi and its not going anywhere.

Its clamped in a 1/4" compression fitting with a steel washer though, not just slotted in a hole.

Threaded valves are easier to put in, just drill a 3/8" hole, put the valve itself into your drill chuck and screw it in.
Rubber pull through valves always seal, because the pressure holds the valve against the inside of the pipe. I have had them at over 180 psi with no blowouts. They're easier to get, because you can just go to a bike shop and ask for all the popped tires, which they usually give you for free. Cut out the valve and pull it through a hole with pliers.

mine has never leaked and i take it past 60 every time i shoot

i would prefer to use a treaded one tho like they^ said can hold allot of pressure and can be made air tight easily

i prefer threaded schrader valves because they are safer, and can handloe higher pressures.
