Permatex part number 51031 is a high temperature anaerobic flange sealant supplied in a 50 ml container. Formulated specifically for rigid assemblies, it cures in the absence of air to create a leakproof seal between mating flanges. The sealant withstands temperatures up to 400�F (204�C) and fills gaps up to 0.020 in. when used with primer, making it well suited for gasketed joints that must maintain clamping loads under heat cycling. Use it to dress or fabricate gaskets in drivetrain and engine-ancillary assemblies where standard RTV compounds fall short. Call us to confirm this is the correct sealant for your application.
