Tesla ½" Telescopic TRV Extension Piece 25-50mm is rated 3.9 out of 5 by 21.
Rated 5 out of 5 by from Existing pipework There are a must when you can't move the existing pipework on old rads. Transitioning from imperial rads to metric ones!

Rated 5 out of 5 by from Brill solution to problem I have just fitted two 'designer" rads to existing pipework on a tiled floor, so no way to move the tail pipes. Used the 25 - 50mm on one and the 25 to 70mm on the other and both worked perfectly. Job done!

Rated 5 out of 5 by from Good value, easy to fit Used one of these on a replacement radiator which was slightly narrower then the original and it made refitting a doddle. No leaks initially, too early to rate longer term performance but seems a good strong design.

Rated 4 out of 5 by from Very handy Although you may wonder how will this not leak it works very well. You will probably need to wrap a lot of pipe tape around 1/2" thread (about 20 wraps) to be safe.
