The shaded parts on these diagrams illustrate where thread sealant is applied on a variety of assemblies:

Applied as a paste to the threads of nuts, bolts and mating surfaces of fittings before assembly, Loctite Thread Sealant PST Stick keeps parts sealed, even when vibration occurs and temperature changes. The sealant also prevents rust or other corrosion from forming. Nuts and bolts that aren't corroded last longer and can be taken apart more easily. Standard hand tools can break the adhesion of the sealant, allowing you to remove treated nuts and bolts, which then can be reused.

This thread sealant is anaerobic (hardens in the absence of air) and requires contact with an active metal to cure. Active metals (those that tarnish, corrode or rust) include brass, copper, bronze, iron, soft steel and nickel. If both parts to be joined are made of inactive materials, Loctite Klean 'N Prime primer must be applied to one of the surfaces for curing to occur. Inactive materials include plated parts, stainless steel, galvanized steel, magnetite steel, pure aluminum, titanium, magnesium, gold, silver, plastic, cadmium, Iconel, zinc, natural or chemical black oxide and anodized aluminum.

Note: Thread Sealant PST Stick is not for exhaust sensors. An anti-seize compound is recommended for exhaust sensors. Thread Sealant PST Stick can corrode some synthetic rubber tubing.
