Pura shower head - too much weight for a tiny thread

[Stu Thomson]

Hi there,

Hopefully someone will be able to help me…..

I have what I believe is a pura shower arm which has recent started leaking from the fitting which is really no wonder when you compare the weight of the shower arm (let alone the additional weight of the shower head) to the tiny female thread within the arm- please see photos.

I am looking to obviously stop the leak but when screwing the arm to the brass fitting it does not tighten up sufficiently as it over threads.

I have tried to pack out the square chrome backing plate (to get the threads to bite) but by doing this it is not sealing against the o ring on the brass fitting.

Looking online all of the replacement shower arms have a substantial male thread which would no doubt tighten up and be sufficient to hold the weight of the arm/head. I cannot find a replacement one like I have but with a thicker thread (so it doesn’t over thread).

As per the photo the brass fitting is behind tiles. There is a hex end to it but it doesn’t not appear to be separate to the main ‘golden’ brass part.

Any suggestions would be greatly appreciated as to what I can do.

Many thanks

Stu

No photo shown.
It is usual to apply ptfe tape or loctite 55 thread to the male threaded part - then it won’t leak.
