Rubber Gaskets

Rubber gasket is a common sealing element, usually made of rubber material. They are soft, elastic and corrosion-resistant and are widely used in various industries and fields.

The main function of rubber gaskets is to provide sealing at connections to prevent leakage of liquids, gases or other media. They are often used at the connections of equipment such as piping systems, valves, pumps and vessels to ensure sealing performance and prevent the entry of external impurities. Rubber gaskets are usually placed on flange connection surfaces or other connection parts to achieve sealing through pressure and deformation.
