Thread: Any Plumbers here?

Paul, is it a type of Glazing Putty sort of stuff with a cement %?


If these things go hard more often than not the "new additive" doesn't really penetrate & blend well but you would have thought of that already being a Fridgie.

More a sort of putty,no cement.Wont set hard,sort of thick soft texture,although as said my tin of the stuff is a bit dry.

Its good with larger joints with Hemp,which was its main use years ago,but i use it on smaller domestic threads and gaskets.

Works very well,no leaks once its on.Fantastic stuff.

Water only can't use it on refrigeration equipment.

Right, got it. It does sound like a bit of a semi-dried out tub of Selleys Glazing putty in my shed.


Might do the same job?? I can't find your one on Google so makes me wonder whether it still is available.

I am a firm believer in using Black Bitumastic Thick Roofing crap on joints. Never use STAG or similar but do use the Pink Teflon Tape (when absolutely necessary) I found that Bitumastic had been used on old pipework here 30 years ago minimum & have used it since. What was good for the old Market Gardener blokes for the irrigation pipes was good enough for me & it did take the Piston Pump pressures ok. And it still is.

Not available anymore,some health issue if you ate it i believe

We use it on top of teflon tape,particularly where a BSP brass fitting screws into a polypipe fitting,and the thread is pretty lose to start with.Even with heaps of teflon,they sometimes leak.A bit of Flexment smeared over the teflon,it will never leak.

As said,also on gaskets.

I recon maybe some sort of oil may mix with it,but don't know.

When i run out of it,i could try the good old blue Leak Lock,i wonder if that will work over the teflon on water?
Suppose there is only one way to find out...It certainly works well on BSP threads on refrigeration equipment,but have never used it on gaskets.

Yeah sure. Like we all would go around having 3 course meals of Flexment?

Not sure about the leak lock as I found im my latter work years it did seem to lose a bit of sting & appeared a tad "diluted" but prior to that I used a Lead Based one (? name but similar to LeakLock Thread Lock, Thread Seal???) & the lead component would obviously squeeze in to the thread. Ok for fridgie stuff but not used on potable water but a good idea all the same.

Now that one we used for Dessert 'cos in those days we were Supermen & impervious to much..


BTW & with respect, wouldn't you Leak Lock the thread after degreasing & roughening it & then apply Teflon over that or have I misunderstood?
