I know that threaded schrader valves are commonly available, but before i could find one i decided to make one.

Materials

Standard tire fill schrader valve
Male 1/4" quick connect plug
valve core remover
Solder
flux
Razor blade
hacksaw
sandpaper
torch
drill

Procedure

1. Use a razor blade to remove all of the rubber from the schrader valve.( the rubber seems to dull the blade so you might need a few)
2. Chuck the remaining brass part of the schrader valve in a drill, use sandpaper to clean up the end of the valve and reduce the size so it will fit in the male quick connect fitting.
3. Test fit the valve in the fitting. It may be desired to cut off part of the fitting so it is shorter. If so do it with a hack saw.
4. Once the valve fits closely in the fitting apply flux to the valve and the fitting and fit them together.
5. Remove the valve core.
6 Use the torch to solder the valve to the fitting.
7. Allow the the fitting to cool then reinstall the valve core.

I did the exact same mate, was just telling a member to do it about an hour ago lol. Great write up, I have tested this to 250psi, should be capable of a lot more :thumbleft:

How about

Take the razor, get rid of the rubber, get the right sized thread cutting die(M6 or 7 does a good job of it) and tap away....


Or

buy em, so much easier...

Anyway good job for improvising with the materials you had.

I never thought of actually cutting threads on the brass piece, Good idea.
If I had to do it again I would try to use a brass plug. Sine it is the same material as the valve and it is easier to work with.

I tried and took of too much material, was aiming at M6, and cut intot eh tube and so ruined the valve so be careful. Buts its nice to cut em, its alot more simple.
