HIGHSIDE LEAK LOCK® Pipe Joint Sealant

Leak Lock® is a state of the art high strength, pipe joint sealant consisting of chemically resistant film formers, plasticizers, reinforcing fillers and solvents. 

After joints are assembled, Leak Lock® sets to form a chemically resistant flexible fluid-tight seal. 

Ideal for joining dissimilar metals and other materials.  Leak Lock® is a proven formulation that will stick to all clean surfaces and can be used to prevent vibration from loosening nuts, bolts, plugs and fittings.

Leak Lock® should be applied to clean joint surfaces, either with the included applicator brush or any convenient spatula. 

Apply Leak Lock® to both mating surfaces. Tack should be allowed to develop before joints are assembled.
