Anybody use this?
If so what do you use it on most and what’s the verdict ?
Just bought myself a bottle.
Pricier than I expected 😵

Brilliant from memory I think @ShaunCorbs Told me it can be used on any metal thread as long as it’s clean

 

[ShaunCorbs]

It’s brilliant it might be expensive but it’s guaranteed first time I’ve never had a problem and can be removed easily

So would it be suitable for example for screwing a bayonet fitting into a wall plate elbow ?

 

[ShaunCorbs]

Yes

I just used it there, it’s done the job.
£20 a bottle or 40p for a roll of tape though 😱
I’ll see how long it lasts me.

The only bad thing is once set. If you crack the fitting. That whole fitting has to be done again.

How long does it take to set ?

It’s gas tight instantly but if you want it at a special angle normally an hour to be hard

 

[Harvest Fields]

It says cure time is 1/3 hours. But I have been told you can get an activator that speeds that up

I haven’t used it on gas yet.

Ive used it for over 20 year and not had one failed joint. Instant low pressure seal on gas

 

[Chalked]

Haven’t used anything else for 3 years.

It is a bit scary at first

Popping your cherry is an ordeal

Numpty question, as I’ve never used it... could you use it on 1/2 rad tails straight into a cast iron radiator?

Mmmmmm, that’s good to know. I’m currently doing a job, where I’ve got lots and lots of repro cast iron rads with polished brass valves. I would’ve boss white and hemped the threads
