Thread-Magic Anti-Seize compound helps avoid stuck bolts caused by rust, galling, and stainless to stainless or aluminum to aluminum connections.  On our bolted stainless steel tank fittings such as Norwesco Tank Fittings and Rhino Fittings, and on the stainless steel studs of plastic fittings, you MUST use an anti-seize compound on the threads prior to assembly.
