Hi
I had a new towel rail fitted in the bathroom last year. When decorating I removed the rad, and refitted when finished. After bleeding the rad, I noticed that the bleeding valve was still leaking. I tightened it more and have now knackered a washer/o-ring. Its the first time I've seen this kind of washer/o-ring on a radiator bleeding valve.
Does anybody know where I can get a replacement, or what size I should be look for???
Thanks
