Dual fuel towel rail adapter - tightens to wrong position

Hi All

Probably a real simple answer but I'm stumped so thought I'd ask on here.

Currently fitting a dual fuel towel rail, all is ready but when I fit the element and the dual fuel adapter, the heating pipe inlet is in the wrong position. It has no wiggle room to tighten it up another half turn and doing a half turn less leaves it very loose.

It's a single threaded adapter so not a case I can just Retry and pick up a second thread.

Any ideas what I can do to overcome this? Do they have adjustable versions or different size threads so it would turn another half turn?

Suggestions appreciated.

Cheers. Karl.

Copious amounts of Loctite 55 .

Or if you're old fashioned, hemp.

Silicone will do it; onto clean threads if the fuel elbow is left overnight to set.

Or Fernox LSX.

My preference is hemp, cunningly applied to a roughened male thread and then disguised with PTFE tape.

These fuel elbows have a parallel thred and are indeed awkward to seal as your rad valve orientation prevents winding in that last half turn.

There may be other Loctite products suitable, all will require clean* surfaces.

Thank you very much. I'm glad it made sense and you understood what I meant.

I was thinking LSX so will have a look what I have available tomorrow.

Thanks again for the response.

Loctite 55 is by far your best option, it's very good at thread alinement.
A Plumbers' Merchants may have a sample they'll give you FOC. I know of one DaftyDIYer that got a wee sample & that was all he needed......
