Sparkplug Boot Tubing

[stevielewis]

I'm sure somewhere this has been addressed but I don't seem to be able to find it. What is the outside diameter of the popular 1/24, 1/25 scale sparkplug boot tubing? I don't have any in my supplies so I can't measure it. Any help with this will be appreciated. Thanks.

As a side note, without purchasing aftermarket items, what do you use for wheel valve stems, wire or plastic? what size diameter and length?

The boot material I use is .032 black or red "live rubber" tube that I got at a fly fishing store for fly making.
I myself use K&S brass .020 wire for tire valve stems. Costs about 25 cent for a 12inch piece. I cut to the length I want, file the end flat and with the brass wire I can bend 45 or 90 degrees or leave it straight. Paul

Thanks, Paul. That's the information I needed.
