I've got a couple of valves that look a lot like these:
(They fell out of the plumber's van so I do not have a make)
Anyone know where I can get non turny caps for those? This rad is supposed to stay on as a shunt (though we do have an auto bypass as well so not going to blow up)
The valve stem ends in a square rather than a rectangle. Just need nice chrome caps that don't allow the valve to be operated - they're too easy to knock right now.
