My pressure gauge part of the tool kit on my 2600 spider is missing its tip / The end piece that screw onto the tyre valve. I have found some steel tube which matches the missing bit and I need to cut a thread into it which matches the Shreader thread - does any one know what thread this ?

A webs search gives

Schrader valve is 7.7 mm (.302") x 32 T.P.I. Which is the std valve thread size for all modern cars , push bikes etc but this is too small. First photo is correct end

Photos attached to show the thread I'm looking for.
