Rated 5 out of 5 by from radiator fitting Excellent concept when fitting radiators. Quick and easy.

Rated 5 out of 5 by from Great piece of kit Very handy when replacing older rads with newer more efficient (and unfortunately smaller) ones. The only down side is that my first set only lasted 18 months before needing to be replaced. Hoping these ones are in for the long haul.

Rated 5 out of 5 by from Magic How do you make a watertight telescopic seal? Magic, that’s how!! ... fitted easily allowing for a far bit of wiggle room and no leaks after a week. Well done manufacturers. Usual high standard of service at the store during difficult times as well!!

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
