Towel Radiator Element 400W
flawed elbow design
The elbow replaces a 1/2" BSP stem where the valve has 360deg freedom. The elbow is a O ring design where the final inlet alignment cannot guarantee an O ring seal.
No wonder two of the reviews refer to leaks. The instructions say (in red) "Always use PTFE tape ... do not JUST (my emphasis) rely on the O ring seal.
That is nonsense, a design should either be PTFE or O ring. I have never had a 1/2" BSP O ring seal blanking plug or bleed valve leak.
So I used liquid PTFE in preference to tape. No leaks and a hot towel rail.

Great value, have fitted 1 of these and have another one to fit, no leaks here... guess I plumbed it in properly. Do not forget to get the elbow with your T if you want it symmetrical.

needs some work
I installed this with no leaks on my new pipe-work. When I can to pressurise the system the element leaked from the inadequate "o" ring at its connection. Even after tightening it still leaked. Luckily I had some spare "o" rings to add to the existing one to seal it with no leaks. The product needs some testing and improvement. Only the "o" rings let it down. I lost a dose of inhibitor as it was drained out.
