Blank Nut ½ x is rated 4.7 out of 5 by 27.
Rated 5 out of 5 by from Cap It Cheap Fix, did the job well, handy to keep a few spare, never know when it will be needed.

Rated 1 out of 5 by from Beware I bought one 3/4" and one 1/2" - the former had a washer and I assumed the latter was the same. Didn't check, unfortunately, and it cost me a sodden carpet, a lot of hassle, and money. So make sure before you buy.

Rated 5 out of 5 by from Blank look Worthwhile keeping a couple of these in your kit. Use them to seal radiator valves (3/4" too) when you remove a radiator for decorating etc to ensure there's no drips. Same for isolator valves which often weep too or just to keep debris out of the fittings.

Rated 5 out of 5 by from Good Blanking Nut I wanted to permanently remove a radiator in an airing cupboard, and used this to blank off the pipes. Supplied with sealing washer and it did the job perfectly. Can't go wrong.

Rated 4 out of 5 by from Blanking nuts As per other reviewers I needed a couple of these when removing a radiator. Rubber seal inside helps although easy to lose. I keep mine in a small container when not in use. Price at the time of purchase was great
