Lock tight

Very good quality Works well no air leaks

Excellent Stuff

I have always used PTFE tape on radiator threads but this is easier and quicker to apply and so far after maybe 20 fittings has been 100% effective. It is quite expensive but if it saves the time fixing the occasional leak or getting a call back it is well worth it.

perfect stuff....wont use anything else

so i work on steam heated industrial washers and dryers and got fed up with ptfe tape being a pain to apply or it failing on the first week..this stuff is easy to apply and sets almost right away ,can handle the high temps from steam and holds the joint perfectly..and u can still remove the threaded joint and easy to clean off..great on any compression olive fittings...its a little expensive but then so would having to restart the whole job a week later.its never failed to do the job..

Not 50ml

There is no way near 50ml in this bottle as checked inside,lucky if there is 15ml,very expensive for amount supplied,don't let the size of bottle fool you,will be buying elsewhere in future,bottle may be 50ml but certainly not the contents
