Unbranded - 5188 - Sealant

The Permatex 5188 Anaerobic Flange Sealant is a high-performance, non-corrosive gasket maker designed for use on rigid flange assemblies with close-fitting parts. This semi-flexible sealant cures in the absence of air when confined between metal surfaces, creating a durable, leak-proof seal. It is resistant to oils, water, and common automotive and industrial fluids, making it suitable for a wide range of applications where a reliable, chemical-resistant seal is required. Ideal for sealing rigid machined flanges on transmissions, engine casings, and pump housings.
