Rated 5 out of 5 by from Great for radiator valves I bought a couple of these to seal off thermostatic radiator valves which dribbled when the radiator was removed. The nuts come with rubber seals so you don't need to buy anything else. Just fit and tighten. No dribbles!

Rated 5 out of 5 by from Panic Reliever The plasterers had started when a shout came, leak in the hall ! Oh no. As I ordered this product to 'click and collect a second voice said 'leak in the bathroom' Oh no ! No problem. Screwfix had the answer in stock. After a no fuss collection I was back fitting the product to stop all leaks......instantly. No damage done. I will keep these in my plumbing box for the next decorating session. Thank you Screwfix.
