At one time Tracy Tools had the taps 'cos I've got some somewhere, and the little tool to get the valves out ...

Looking a bit doubtful now though ...

Hi krv,
Just been thru the same exercise! I have one of the little tools to install / remove the valve it also cleans & cuts thread. I tried & couldn't get a seal. More googling & I found that you also need a taper or the seal to work!! So I cleaned the rubber off a tire valve stem, drilled out my home made fitting & loctited the stem in, works just great!
After doing this I found out that you can buy a fitting with the valve in it! check out your local hydraulic or phenumatic supply shop.
