Type of trv

[joesoap13]

Hi guys, can anyone tell me what type of Trv this is.
The fitting on inlet isn’t coned, it’s Leaking on pin when closed.
Lockshield on other side same, but should be straight swap?
Is it 15 MM to 1/2 inch ? Only ones I seem to be find ! Looks like 15 mil to 20 mil ?
Like using imperial still . Luddite.
Would like to change it, and others, same problem,but does this mean changing inlet pipes as well, cannot just swap new for old body, larger fitting on rad as well.
Cannot find any similar ones
Tower is the make.
Cheers

Any 15mm x 1/2 " bsp TRV WILL DO, the LS is different but just buy a complete L/S and change the tail over, lots of makes sell both valves as a pair and not expensive

Meant to say in the last post the 15mm refers to the compression fitting between the pipe and the valve, the 1/2" is the thread size where the tail inserts into the radiator, that is where it is confusing

Cheers Ian.
On the Trv , the fitting on the pipe is not a standard compression, 15 mil, so, presume will have to cut the pipe below it and use a new one, if there is enough pipe to pull up from below floor ?
Cannot just change the body of a new one ?
Got three like that leaking ! When closed, need changing.
Can on LS.
If not, renew pipe to elbow underfloor.
So many types of fittings in house, never noticed the difference in compression on Trv side .

When you undo the nut , the nut will drop down and reveal the olive, cut the olive off using a junior hacksaw, best to cut about halfway through then split using a flat blade screwdriver, dont cut too deep that you damage the pipe, then remove the old nut and the new set will simplt fit on.
