Rubber-steel gaskets, also known as rubber-metal gaskets or rubber-coated metal gaskets, are a type of gasket that combines the properties of both rubber and steel to provide effective sealing in various applications. These gaskets typically consist of a metal core with a layer of rubber or elastomeric material bonded to one or both sides.

The metal core of rubber-steel gaskets provides mechanical strength, stability, and resistance to deformation, while the rubber coating offers flexibility, resilience, and sealing properties. The rubber layer helps create a tight seal against the flange surfaces, even in applications where the mating surfaces are not perfectly smooth.

Rubber-steel gaskets are commonly used in industries such as automotive, machinery, appliances, and plumbing, where they are employed in sealing applications such as engine components, pumps, valves, and pipe connections. They are suitable for a wide range of operating conditions, including moderate temperatures and pressures.

One of the key advantages of rubber-steel gaskets is their versatility and adaptability to different sealing environments. The combination of metal and rubber provides a gasket with the strength and durability of metal along with the sealing capabilities of rubber, making them effective in sealing against fluids, gases, and other media.

Rubber-steel gaskets are relatively easy to install and can conform to irregularities in flange surfaces, providing a reliable seal with minimal tightening force. However, proper surface preparation and installation procedures are essential to ensure optimal performance and prevent leaks.

Overall, rubber-steel gaskets offer a cost-effective solution for sealing applications where a combination of strength, flexibility, and sealing performance is required.
