I also looked for a schrader valve recently. I ended up using the thread of a Dunlop valve: http://en.wikipedia.org/wiki/Dunlop_valve#Dunlop_.28or_Woods.29
Basically I went to my friendly local bicycle repair shop, got an old inner tube for free and cut the valve stem out of it.

It seems that the Schrader and Dunlop threads have the same diameter. Fits perfectly in the hole for Schrader valves on my bicycle pump.

Dunlop valves are used widely in Germany and the Netherlands, so if you happen to live there... 8)

Isn't Brian from the Netherlands

well it seems that this is a form of old bicycle tire valve, it doesn't say anything about the use in cars does it? well 50psi does kinda suck so I doubt it,
If you wan't go to the guy that does car repair/tire replacement for you or your parents, or ask your friend who has a car to pick some up

SNDM wrote:How much stronger are the brass (or any metal) schrader valves compared to the rubber shrader valves, in terms of psi?

EDIT:
I just cut open one of my rubber schraders, to get at the brass core, so that I can solder it to my copper gun.
Is this stronger than using the rubber stopper method it had to begin with?
Or am I just wasting time and valves?


Think about it. Metal = stong , Rubber = not so strong. The metal/brass usually have a higher psi limit.
