You should get one from mcmaster. by the time you pay for shipping it will be the same price and if you order from mcmaster you will have your valve the next day if you order early enough in the morning!

Free shipping from hong kong equals you will get your valve in a month!!!!

If you order from mcmaster it would be about 10 dollars more, so you choose faster shipping and a good valve from mcmaster for 10 dollars more or the other valve and probably slower shipping for 10 dollars less. I'd spend 10 less dollars 8)

Included with the 10 dollars less, a valve that has been used at high pressures such as 500 psi.

Warhead makes a good point. I've never heard of the mcmaster diaphragm type QEVs being used at high pressure.

I used mine up to 250 once. it survived, but i can promise yours will. Like i said that was for 1 shot at 250 psi.

I have, I found 150 bar is the breaking point for the diaphragm in the 1/4" ones

Hmmmmmmmmmmmmmm?? Are those valves found on E-bay serviceable though??? It does not look like they are. The deltrol brand mcmaster sells are!! If you needed to put in a new o ring or diaphram you could!!

Go forthis one. I doubt it will take more than a couple of weeks to arrive, it will probably be sent by small packet airmail.
