Valve Stem

I'm trying to pressurize a cast iron radiator ,I've got a tire valve stem that's .45 inches in diameter. What
size hole should I drill in the plastic plug cap for the radiator to get the valve stem to fit right? Thanks.
how else could I do it?
call a garage and see what size holes are in tire rims...or if you have an old rim around , find the drill bit that will fit the hole in it...

Bad valve stem seals?
Basic Rules to Choose Suitable Valves For Your Applications - Part 1
In general, specifications, types and working pressure are always indicated when purchasing the valves. However, the information is inadequate for you to buy the suitable valves for your applications, especially in such competitive markets. In order to stand out among the competitors, each valve factory innovates the design and manufacture of the valves, though the basic standards remain the same. It leads to product variations from manufacturer to manufacturer. Therefore, it is suggested to bring up technical requirements as detailed as you can and come to consensus with the manufacturers.
1. Basic Standards
1.1 Valve specifications and types should conform to the documents.
1.2 Product numbers to should follow the international standards. If valve is numbered by manufacturers themselves, documents about the number systems are needed.
1.3 The actual pressure the valves can take should be bigger than that of real applications. 1.4 The valves should be manufactured according to international standards. If produced to manufacturers' standards, related documents are needed.
2. Valve Materials
2.1 Valve body should be made of ductile iron. Material code and testing data should also be included.
2.2 Valve stem should be made of stainless steel.
2.3 Screw should be made of brass or bronze, and its hardness and strength are bigger than stems.
2.4 The hardness and strength of sleeve has to be smaller than that of stem.
2.5 Packing materials differ based what kind of valve it is.
2.6 Stem filler should choose materials which won't deteriorate for decades.
3. Transmission Gearbox
3.1 The body of box is made of anti-corrosive materials, same with valve body
3.2 Sealing unit is necessary, and the box should bear soaking in water of 3 square meters.
3.3 On-off operation only makes valve shaft to rotate, and other parts remain the same.
3.4 There are no unrelated stuff in the box. The connection between gear tooth are applied by lubricant.

Are you speaking about a recip compressor?
Either way the crankshaft turns – rotational motion. The connecting rod attachings to the crankshaft and the piston. It is the piect the converts the rotational motion to linear motion. The piston moves in linear motion and compresses the gas in the chamber.
Not really sure what your remaining questions are specifically referring to. This is hard to describe without diagrams.
I''ve been using Caffelatex since GT first introduced it and let me know where to get it. Two sets of wheels, tubeless and non tubeless tires, Stan's injector, valve stems and tape, outlasts Stan's, and as GT stated, you don,t know it's working because you don't flat. I got lazy, Stan's had given up, just added the caffe and rode, love the stuff. I'm in central Texas, lots of cactus, before tubeless I flatted every ride, no more.
60-80 in/lbs or just as tight as you can get it with a nut driver. at work we never torque em cause they hold up just fine by hand tightening it, but if you had to put a torque spec on it thats about what it'd be.
and enjoyed it.
