Permatex 51813 High-Temperature Anaerobic Gasket Maker, 50 mL Tube

Permatex 51813 High-Temperature Anaerobic Gasket Maker is a reliable flange sealant designed for precision sealing applications where conventional cut gaskets may be difficult to use. The anaerobic formula cures in the absence of air when confined between close-fitting metal surfaces, creating a dependable seal that helps prevent leaks caused by fluid, vibration, and thermal cycling. It is well suited for rigid metal flange assemblies and other demanding maintenance and repair work.
The 50 mL tube provides convenient dispensing for shop, service, and professional automotive applications. Permatex 51813 helps fill minor surface imperfections while maintaining a consistent seal across machined mating surfaces. Its high-temperature performance makes it a practical choice for assemblies exposed to elevated operating temperatures, while its controlled curing action supports accurate application and clean assembly.
Use Permatex 51813 according to the application requirements and manufacturer instructions. Surfaces should be clean, dry, and free of oil, grease, and debris before application. Apply an even bead or coating to the mating surface, assemble the components, and allow the sealant to cure as directed. This product is supplied as a 50 mL tube and is not air restricted or limited to truck freight.
