Radiator Valve Tail 15mm x 1/2" BSP (2 Pack)

Product Information

They tend to get crushed or pushed into the valve and can be a nightmare trying to remove the old washer. Assumign I have read your question correctly, I can't for the life of me fathom how you could have distorted the valve end of the tail while doing up the radiator end. Still, on the assumption that the valve end is a compression fitting, I'd wager that if you can still get a nut and olive on, and if you can still get the end of the tail into the valve, it'll seal just fine. If you want to be paranoid about it, wrap some PTFE around the fitting face of the olive.

Hi, is Plumb Centre a good place to get a reducing bush? There's one fairly close by I should be able to get to on saturday... If it’s leaking from a nut on the bottom or side of the TRV, then you should follow the process above for a “ leaking radiator valve nut“.

What's OP? "¾" thread of the union nut" - that makes sense, but am I looking to replace the radiator tails as well then? What am I going to do if I measure the hole, aren't I going to attach the valve to the tail anyway? A thermostatic radiator valve leaking water from the pin has to be replaced, but if you want a temporary fix, you could try turning the radiator off when it leaks, as this might help until you replace the radiator valve. I started to make up the tail using a 16mm ring spanner - approx 8" long. With about 3 threads to go I needed to switch to a 10" Bacho adjustable wrench to tighten the tail all the the way up. It took a bit of force, but nothing which felt excessive, albeit this is first time that I have fitted radiator tails.

James - many many thanks - one very last question - when I said the lower half, sorry, I meant the first of the threads up to half way. I'd start with 15 to 20 wraps of ordinary (thin) PTFE. Screw the tail in. If it doesn't start to get a bit tight after 4 or 5 turns (threads), unscrew, remove tape, and replace with + 5 wraps (so 20 to 25) and try again. FWIW you might have beena bit shy on tape unless yours is gas tape or something. When I was doing our rads I used about 12 turns of tape, and tightened the tails up so they were still very slightly "on the tape" rather than grinding metal on metal with a long wrench. Maybe force of habit after fitting the outside tap - the first attempt was at a comedic angle until I tried again with more tape. Standard rad tails tend to measure at 15mm, in line with the most common pipe size also being 15mm.
