hi ive got a leak on my tubless rim band its a new rim band but i buggerd the valve. i got the valve out and replaced it with anougther. but know its leaking dont really want to pay anougther £40 for a band. i had the push on rubber typ dust cap on ive just inflated it again. and replaced it with a plastic dust cap i think ive damaged the inside of the valve stem. the valve still screws in but it still leaks any ideas how to stop it leaking? ps would abit of ptp tape seal it?

You can get steel dust caps that have a rubber seal in them. I have one and it works but the tyre leaks through one spoke nipple so it goes flat after a week.

You can unscrew the valve from its housing and fit another. Use two tiny screwdrivers and insert them into the valve, use another screwdriver as a lever in the middle to turn and unscrew it.

Or go to a auto shop and purchase the correct tool to unscrew them and get a new valve at the same time.

There is a common, inexpensive tool available in auto supply stores that will re-tap the threads for both the valve and the cap as well as install the valve.
