Rubber gaskets are sealing materials made from natural rubber or synthetic rubbers such as NBR, CR, EPDM, and FKM. They feature excellent elasticity and flexibility, widely used in water supply and drainage systems, HVAC, food machinery, chemical pipelines, automotive components, pumps, and valves. Suitable for sealing water, air, oils, and mild chemical media.
