"If you need a 15mm blanking nut, then this is the one for you. You screw it on, tighten it up and it stops water pouring out. What more can one say about it? My only comment is that for a small piece of brass it seemed pretty pricey to me - but still cheaper than having water pouring through my ceiling when I removed the radiator in my bathroom."
"I purchased this to replace an old one, the washer had 'dissapeared' and it was weaping, it tried differnet washer etc, still no good, so replaced with this one that comes with what I would call a dsik rather than a washer and noo more weaping \drips, Fab"
"Needed this to block off cold water supply, following the removal of a redundant Electric Shower (No stop-valve fitted of course) It fitted in the restricted space available and worked perfectly-no leakage. Also bought a compression 'end stop' unit with olive, just in case the Blanking-Nut didn't work but of course it did."
"Bought this product, which would have done the job nicely, had I bought the right size! Bought this to blank a redundant hot water washing machine tap, but you need a 3/4", not a 15mm. Be warned. No problem with return for the right size, which was otherwise identical and worked a treat."
