Blank Nut ½ x is rated 4.8 out of 5 by 29.
Rated 5 out of 5 by from Blank Nut for leaking shower. I needed 2 blanking nuts for 2 different leaking showers and wondered if these would do the job. It has done what was needed -so I can now plan for the plumber to come. Very easy to fit and efficient. Very good value for money.

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.
