i read your previous article on the above telescopic radiator vales and this would solve my problem of a 75mm gap either side of my rad and valve. are they compressin fitted and i am not a good solderer.

 

[Biggles..]

yes they would but sometimes leak, solid bushes would be better.

I got some TRVs which came with the adjustable tail connector, I didn't ask for it. You can also buy the tails separately for £3.30. I think they have an O-ring so should form a good seal. I haven't used them yet and haven't looked to see how they work.

I can't see how you'd fit this thing.

This one looks like it fits a 3/4" rad nut and a 1/2" valve. I can't understand it.

Or how about this thing?

Telescopic tailss only good if there is no sidewards presure on them , they have to line up spot on otherwise they leak on the O ring

Chuck those adjustables (middle pic) in the skip - get sick of swapping them out. As namsag suggests any undue pressure will compress the O ring and they will leak. The heat often bakes the O rings 'cos they are garbage.

How does this one work?

 

[namsag]

You screw it into rad add a nut and olive and cut to length req

 

[Gasguru]

Just cut it to the lenght required.

Does the end facing Left screw into the rad threads?

Where does the chrome nut go?
