Permatex® anaerobic flange sealant is a single component, medium strength, thixotropic, anaerobic sealant that cures rapidly. The product cures when confined in the absence of air between close fitting metal flanges. It provides a tough, resilient, solvent and temperature resistant seal that flexes with flange movement caused by vibration, pressurization or thermal changes.

Permatex® Form-A-Gasket® No. 1 Sealant is a reddish brown, viscous paste with a characteristic alcoholic odor. It is a fast drying paste that changes to a hard, semi flexible seal through solvent evaporation. It seals flanges, fittings, connections and assembles against leakage. Improves gasket seal in permanent and rigid assemblies.
