Rated 1 out of 5 by from Failed after 3-4 years These seemed like good value for money, but after 3-4 yrs, two that were installed on radiators have now failed.

Rated 5 out of 5 by from Great product Needed to swap out a radiator which was smaller than the original and these extended enough to meet the pipework. Saved having to move the piping and a lot of time. Have only scored 3* on performance and reliability because this is of now unknown but I think there won't be any later issues.

is there an angled 90degree version?

I don't want to remove old valves. They have side connectors to the old radiator so need side outlet from existing valve to bottom feed towel rail. What would be the best way to connect?
Asked by: dave1220
Hi dave1220, Unfortunately Screwfix do not stock a 90 degree version and I have been unable to find any other retailers online who do. However a stem elbow, such as Hep2O Plastic Push-Fit Equal 90° Stem Elbow 15mm (8137F) fitted to the pipe connection side of the valve may be a solution. Thank you for using Screwfix Q&A.

Hi, These parts are described in the Specifications as 15mm * 1/2 in. The parts supplied are not these sizes do not fit the TRV and the download instruction manual gives the female thread as 3/4. Without checking I think the parts are as per the manual

Can you please advise.
Asked by: davidbar
Hello davidbar, The tails has one female G3/4'' thread and the other is male G1/2'' thread. The diameter of the tail is 15mm. Thank you for using Q&A

Do I have to put ptfe tape around the end that goes in to the radiator.

Asked by: Bikedave
Hello there, You would not need to as the threads should seal but the ptfe tape may help ensure long term sealing of the threads. Thank you for using Screwfix Q&A.
