Is the fitting a tight fit with nothing on?
4 turns per thread or over the entire fitting?

I get the large toothpaste sized tubes from a merchant in leeds £42. Seems a lot, but that whole job used 1/4 of it.

It will hold pressure straight away.but full strength talkers a few hours.

Bss normally

Just read, 3 hours full cure time. That's doable to be honest, but none of the merchants in Lincoln will stock it I bet!

We have a BSS, worth trying them tomorrow.

The thread is definitely quite tight, I can't even get 4 turns of 55 over the whole thread without it binding and becoming impossible to tighten.

BSS keep it.

Thanks all. Need it tomorrow first thing and BSS is round the corner.

That seems like what I need for this job tbh. Give it 3 hours and no leaks. The pipework is feeding the cold water tanks at a small hospital and I've had to leave them isolated but full overnight and tell wards to lock bathrooms till tomorrow. All because Loctite 55 wouldn't work

Tell you what it's like learning all over again, even though they are still compression fittings.

One positive from today - Yorkshire Xpress fittings are brilliant aren't they, made in seconds! I'm a convert.
