"Faced with an old imperial sized radiator to change, with no metric size replacement, found these at Screwfix, so simple to fit and whats more, no leaks Can't recommend them enough, so now no problem if you are changing from an old imperial size to metric."
"Went to my local plumbers for this but they said they only had the full valve... Looked on Screwfix and bought these. Changed a radiator for a larger capacity one and these did the job fantastically. no leaks and worked first time."
"Faced with some odd sized radiators to replace I put the job off for so long I had holes in the rads. Googled the best way to get over my problem and came across the answer. Extendable tail pipes. Quick and easy to plumb in, turned the rads on and no leaks, AND I AM NO PLUMBER. Believe me when I say ordering on the Screwfix site is so easy and you are kept informed all through the process, all ready and picked up within ten minutes. You really couldn't ask for more !"
"Thought I'd have to get a new radiator as the threads were so bad that neither PTFE tape nor jointing compound would stop the leak. Unlike normal tails, these use rubber seals against the face of the rad, so stopped the leak. Don't overtighten them and they are simple to fit."
"Perfect for imperial to metric size conversion allows up to 50mm each side and it just slides in and out for easy adjustment and fast fitment. Took a 1695 rad down to 1600 and a 1435 down to 1400 without changing the valves. Just fit one each side of the rad and slide the tube to where it needs to be and job done :)"
"Great for changing two (very) old 'imperial' radiators to sparkling new metric ones. Just gave me enough leeway to avoid draining down the system to change the pipework and made swapping the radiators easy. No more cold room for me!"
"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."
