Radiator Valve Extension 100mm is rated 3.6 out of 5 by 54.
Rated 1 out of 5 by from Cheaply made I purchased one of these to bridge the gap in a new rad after replacing my older type which was 30 mm wider . The extension snapped while tightening it with a radiator valve Allen key by hand . I couldn’t believe how weak it was . It left the thread inside the rad . I managed to remove it . But I certainly wouldn’t purchase another

Rated 5 out of 5 by from Recommended item This is an excellent product. You need a 12mm Allen key rather than the usual 1/2 inch.

Rated 4 out of 5 by from Why don't they have flats? Sturdy and does the job, except no flats for a spanner so can come undone when doing up the other parts which can cause a lot of trouble.

Rated 3 out of 5 by from Tricky to fit. These extenders are parallel threads and on the looser side of ½”. Use Fernox LS-X with these, as PTFE and other compounds don’t seal the threads!!! Found out the hard way.

Rated 1 out of 5 by from Under engineered Bought six 25mm extensions to replace old radiators with new metric sized radiators, the first two I used both split when tightening. Did I over tighten maybe, but I purchased a different extension from a plumbers merchant and no problem at all and was very weary of over tightening. These extensions from Toolstation are a cheap manufactured product of poor quality.

Rated 1 out of 5 by from Rubbish Brought 4 to fit to 2 radiators and all but one developed a split after a couple of days so Tool station exchanged them for new ones which also developed a split a couple of days after fitting, Be aware they look good when fitted but its after a couple days of use they split
