So costly but very poor quality.
Got a tube which has dried material. Not able to flow out of the tube. So costly but very poor quality. Loctite to please send me replacement.

Using Loctite spray on cleaner primer with this product, guarantees leak free stainless steel pipe connections. After applying the sealer to primed pipe threads, this thread sealer begins setting up within 5 minutes. Polypropylene Glycol coolant defied all attempt at sealing stainless steel pipe connections until I cleaned the pipe threads, applied Loctite Primer, allowed it to dry, then applied a coat of Loctite Liquid thread sealer. No coolant leaks when using this thread sealer on pre-primed connections. I recommend this product for stainless steel, brass, and Iron pipe connections.

This stuff dries hard and very quick maybe in 15-20 minutes but you have to screw fitting ASAP if you wait 10 minutes it's already too late. Also put it only on one side of fitting make one and twist it in right away.

Copper pipe fittings on my hot water tank would NOT seal. Tried all kinds of teflon tape, tightening, new fittings, nothing worked. Found this stuff, followed directions (imagine that!), problem solved. Leak fixed. GREAT stuff!

Virtually nothing in the tube but old dried out material. Completely useless.
