Chrome Radiator Compression Valve Tail 15mm 2 Pack is rated 4.8 out of 5 by 57.
Rated 5 out of 5 by from Exceptionally Useful I wanted to connect two radiators and I wanted to have them firmly on the wall before doing the plumbing. Using one of these in each radiator enabled me to get the connecting pipe into place. Good quality components. I was worried they might leak but they definitely do not.

Rated 5 out of 5 by from thank goodness for these I was having huge problems with the Tesla telescopic - could not stop a small leak on both tail. These are actually telescopic but you wouldn't know from the description. Bone dry first time. I think the fact that there is a flange and o-ring makes all the difference. The Tesla design doesn't have this - the threaded part screws in and there is no seal. Obviously(after reading the reviews!) needed a nut and olive - luckily I had a bunch of chrome isolating valves which I borrowed from. Docked one star because it would be much easier to supply a matching nut and olive on the 15mm pipe side.

Rated 1 out of 5 by from Not robust When these arrived i was immediately worried. for starters the thread is only about 5mm as opposed to the deep thread in a standard tail. there is no space for space tape so you gave to rely on the rubber washer. I only used one ( used inline valves and copper extension form bend for others and was glad i did). water poured from this as soon as the rads were put on. i had to get around by joining 2 normal tails together. my plumber tells me you can get long tails you can cut down to size. Don't buy these telescopic ones you will only regret it.

Rated 5 out of 5 by from Used them on three radiators Used these three times now, first set were perfect first time and today I have used them when renewing two 600x1600 rads. This time when I filled the system and started persurising they all started to weep and leak. I moved the TRV around and got them a little more square, carried on filling to around 2bar and they have been fine since. I'll have to keep an eye on them going forward and am nervous about touching them or hitting the pipes with the vacuum cleaner. Still a great product and I think they seal better once under pressure.

Rated 5 out of 5 by from Excellent I don't usually bother to review items, but am very pleased with this. I have recently converted 8 Imperial size radiators to narrower Metric size using these Tails. None of them have thus far leaked. I am very much an amateur and found them very easy to install.

Rated 5 out of 5 by from Longer radiator tail Very useful when you need the extra length, tail slides in and out for max flexibility, great stuff

Rated 5 out of 5 by from They Do The Job. Bought these thinking they were a rigid assembly that you shortened to suit using a pipe cutter. When fitting I realised that the 15mm pipe actually slides through an 'O' ring to enable easy adjustment. I had my doubts about the tails sealing, but, hey ho, no leaks so far after being in use for a few days now. Getting the valves to stay upright due to the flexible plastic feed/return pipes is a pain as it can freely rotate on the tail (should be OK with copper) I do expect them to start leaking over time, especially after being knocked a few times with the hoover. I think Screwfix should stock rigid tails as I'd much rather had fitted a non adjustable tail. I've noticed on the forums that some plumbers will, once adjusted for length, run a bead of silicon sealant around the inside as an added precaution.
