Schrader Valve Tooling

[Mike@Dive Lab Inc.]

I have a custom Schrader Valve body to machine. The .210-36 taps for the internal thread are available off the shelf. Does anyone know if there's a form tool available that will cut the internal features? The tool will look similar to a MS O-ring port tool. There's a conical seating surface below the threads that is critical on the surface finish. I have a 1000 parts in 316 stainless to make so having a custom tool made is no problem. I figured I'd check with you guys before getting quotes on custom tools.

 

Thanks

My first stop would be Harvey Tool

Thanks. Harvey is my go to also for stuff like this. They just changed the material to 464 Naval Brass which makes things much easier.

I have used these guys and would not hesitate to again if the application were to arise.

Tools like this are frustrating to me. With the millions and millions of these valves being made, one would think there would be an off the shelf solution for tooling. Finding that solution is tough....

I wonder if PH Horn would have something.
