Loctite 518 is a flange sealant and gasket eliminator designed to create reliable, leak-proof seals on rigid metal flanges without the need for traditional cut gaskets. It fills surface imperfections and gaps to deliver durable, chemical-resistant joints ideal for industrial and MRO applications.
This 50 mL tube is well-suited for use on gearboxes, pumps, compressors, and other assemblies where flange sealing is critical. Its anaerobic formula cures in the absence of air when in contact with metal surfaces, providing a strong, flexible seal that resists oils, fuels, and shop fluids.
