I used this megaloc generously when installing a new home oil burner furnace. I used all new pipes during this install and now 1 year later more than half of all the black pipe threads have developed leaks. Save yourself the headache stick with what u know works.

Hi;

Purchased Megaloc Multi-Purpose Thread Sealant to use on the pipe fittings on my hot water system. Out of 6 fittings 3 leaked, Could no tighten to stop the leaks. New fittings, Stainless steel tank. Like some mentioned in one of the reviews, comes off your hands and clothes easily, including pipe threads. I stired it , thinking it had settled out,no effect. It is really thin, I had my doughts about it while using it before I turned on the water!
