Leaky joint question

[Staplebrau]

Our electric shower broke, so i've replace the unit with almost identical unit. The problem is that now i've installed one of the joints is still a bit wet, a droplet forms every minute - so its not a running leak or a major problem - but i want to sort it, to stop future issues or wasting water.

To give you an idea - the copper feed pipe comes out of the wall, which has the original olive and nut on it. I have now attached the new shower to the feed pipe via a female elbow joint (I believe this is the right name).

Its the joint for the feed pipe to the elbow thats a bit drippy. I was thinking of just using some FTPE tape on the thread, but would that sort it? Maybe the olive needs repositioning? The nut is as tight as it will go, by the way.

Any advice would be apprecaited.

One wrap of PTFE around the olive (overlapping the edge thet goes into the elbow) should do it.

Good man, thanks for the advice - i shall try it later when i get in!

And if this doesn't work the hacksaw off a few mm of the copper tail. If it's a new elbow, then the stop-depth of this may be marginally different to the old one and be preventing the olive from being pulled to its rightful position.
