Magnet Packing is a seal between two surfaces in an engine or mechanical system that is made from a metal substance, such as steel or copper. In high-performance or high-temperature applications, where other types of gaskets might not be able to withstand the conditions, metal gaskets are frequently used. Our Magnet Packing can be flat, ring-shaped, or have multiple layers, among other shapes and sizes. Make sure the surface is clean and free of debris before installing a metal gasket.
