Are there any available? Closest I can find are some Stans for Hugo fatbike rims but nothing else really.
Its for a friend with some old shimano UST rims. I have all presta on mine so its not something I have ever thought about before now.

I Have got a spare set of presta valves I can try for him which I guess will be fine.

Cheers

Think stand is some when I got some years back but didn’t fit the profile of my rim. If you have presta valves maybe try a few squares of of inner tube with a hole cut I the middle to take up the extra space around the valve hole. I tried presta valves on a Schrader rim and they blew through the hole once up to pressure.

I had a play with some Stans presta valves in schrader rims the other night. Looks like they should be OK.
Also found some lockrings that had a stepped section that fitted snugly into the wider hole.

Got mine from the local garden machneryshop/bike shop.
