"Changed my cloakroom radiator and hada small gap between new radiator and valve. Didn't want to re-plumb the valve and so brought this. Did the job nicely. Trimmed easily to length and simple to secure. Would recommend this."
"Replaced a single radiator on the landing for the very first time. Previous one had a leak on the top.
As the new radiator (Product Code: 71626) was narrower than the old one, got these adjustable extensions. (Do not, as I did, get the radiator Compression Valve Tail 15mm Product Code: 1095). It is also adjustable, but has only threads on one side.
Screwfix promptly exchanged it.
Screwed the end with the bigger nut onto the radiator, and then pulled/pushed the inner tubing to reach the pipe. Screwed it in using Ptfe tape.
For a complete amateur it took me about 5 minutes."
"Unlike some other reviews this worked a treat and hasn't leaked although only been 24hrs since installed but as it's on a pressurised combi system run at full heat and hasn't leaked yet all looks good. Used to replace existing imperial rad with shorter metric rad, note that this will not connect to a TRV, only the lockshield valve (Product Code: 33920). I used this union version on the lockshield valve side and the compression version (Product Code: 10954) on the TRV side."
"Bought this to allow me to fit new metric sized radiator in place off imperial sized one.Seemed like a good idea to save having to alter pipework Found that the valve tail fitted into the radiator OK but the connection on the valve tail (22mm) was too large for the Danfoss TRV (15mm)fitted to the pipework Perhaps this should be noted in the product description"
"Basically there is one fatal flaw in this product: it leaks. It leaks where the screws slide along the pipe. All of them leak. Out of four I bought every single one leaks. Some leak on both sides even!
So, why give it 5 stars? Because for some reason the reviews are coming up "Highest rated first" instead of the normal "Newest first". So I've given it 5 stars in the hope someone will read this instead of buying this product accidentally like I did.
Obviously this was once a good product, but no longer. Go to the top and sort by "Newest first" and you will see all the results are bad until mid 2012 after which all the reviews are good.
"Great solution when fitting radiator of a slightly different size. I had to replace a radiator with a length of 750mm with a smaller 700mm one and this extending tail valve saved having to resite the pipework."
"I was replacing old radiators which were slightly wider than the ones I was replacing. These make this easy without having to alter pipe work I actually bought the wrong ones, I had to swap them for the Compression Valve Tail (these not fit std radiator vales) But the idea is the same. great product"
