Rad valve leaking from spindle

[lmsava]

The valve on my towel rail has started leaking from the spindle. I removed the gland and the spindle and it doesn't leak quickly, just drips a little. The spindle has two rubber O-rings on it. Can I repair it? I've heard PTFE tape might do the job or some sort of packing material.

Thanks

Other than replacing the O rings with the correct ones, any repair is a botch.
If they happen to be Belmont valves you can get the O rings from the manyfacturer (Pegler). Othrwise you have to measure and find 2 the right size. I think I carry about 150 different sizes of O rings!
New valves needn't be expensive if they aren't posh ones.

The valves were pretty pricey in the first place and the missus won't let me get away with a cheap replacement. Where can I get the O-rings from? Would I have to go to a specialist plumbing place or will the hardware shop sell them?

So I wrapped PTFE tape around the galnd nut and it seems to have stopped the leaking. Will this just be a temporary solution?
