Rated 5 out of 5 by from used when rplacing rad had to upgrade rad onto 8mm microbore and this worked to save bending pipe into 15mm danfoss trv valve and risking deamage that could have resulted in lifting the laminated floor if so

Rated 5 out of 5 by from Useful union Replaced a towel radiator slightly different to original and this solved the problem of the gap difference between valve and rad where the pipes project out of wall with no flexibility. Saved a lot of work. Neat piece of kit.

Rated 1 out of 5 by from Don’t waste your time Can’t believe all the 5 star reviews. Leaked from day 1 on a pressurised system. Local plumber has told me he sees it all the time and would not fit them. Don’t chance it

Rated 5 out of 5 by from Very handy for adjusting rad t No cutting required the thread moves up and down the tail so very handy for getting into position without moving any pipes.

What jointing compound would you recommend for installing these?

Asked by: Dogtanian
Hi Dogtanian Thank you for your question. We do not normally recommend the sealing method as there is a lot good products and they all work well. Maybe look at part number; 21548, 7619J or 53863 Hope this helps

I bought this item and installed it on a new radiator. Since the 1/2” thread part doesn’t have an end stop or head, then I’ve just used PTFE tape to secure it. I’ve noticed there’s a few drops coming from that point and I’m wondering how I can stop them

Asked by: RobSay
Hi RobSay Thank you for your question. If you still have small leak in the radiator, it would be best to remove the fitting add more PTFE or jointing compound to the thread and remake the connection. The average turns on the 1/2" thread (rads), with standard PTFE tape is between; 12 - 20 turns. Hope this helps

Do these have to be cut down to your required size ?

Asked by: Bobbyg900
Hi Bobby Hope you are staying safe. You so not have to cut them down as are telescopic. If you want one to cut down to size please look at the following part numbers; 2456R or 599HF (they are rigid) Hope this helps

I've installed this but it's leaking from the rad. The stud end is screwed in tight but still leaking. Do I need to use PTFE tape?

Asked by: JontyQ
