Rated 1 out of 5 by from Poor quality product Have to agree with the earlier posters. This are very badly made even though they're stamped to EN1254-2 Standard. replace 8 Rad's and had 7 leak. Did them with more PTFE and some leaked. After comparing the threads to a standard tail it seems the threads are bad made with flats across the thread peak. Have now contacted 'Tesla' and they have admitted that 12/18 months ago they had a problem with manufacture. So some old stock still around.

Nut size and flexibility

Nut size please. I have a 3/4 valves I need to attach to. Also does it adjust slightly out at Rad 10mm further forward
Asked by: Georgepig
Hi George This item used a standard 15mm nut and olive to compress onto the tail. This extension piece will not work for your installation Hope this helps

How do I secure the olive to the end of the extension? As is stands the nut and olive just slide completely off whereas the original size tail that I am replacing the nuts it located in between the radiator tail thread and the pre secured olive.

Asked by: Redarmy9
Good morning Redarmy9 By tightening the nut on the valve that will compress the olive down to grip onto the tail of the extension valve Hope this helps

Is this suitable for a double Stelrad radiator?

If not can they be cut by a mm to fit? ;)
Asked by: FamP
Good morning FamP The threads on the Stelrad rads are 1/2" so should fit no problem. If you need to cut the unit to size please look at Screwfix part number; 2456R Hope this helps

Use with 15mm Drayton TRV

The telescopic part slips in and out of the olive/screw cap part of my 15mm Drayton TRV extremely easily. I can use PTFE tape and/or sealant but it seems too loose for that to work. Please can you confirm the right approach?
