Hardware Parts (Combined Gaskets) are sealing components made by integrally bonding and vulcanizing a rubber inner ring with a metal outer ring. They are mainly used for static sealing in threaded and flange connections.
Their core function is to prevent leakage of media such as oil, fuel, water and chemicals, while combining the support performance of metal parts and the elastic sealing property of rubber.
Functions: static sealing, high pressure resistance.
Mainly suitable for hydraulic oil, and can also seal water, fuel, etc.
Materials: rubber is mostly NBR or FKM; metal rings are treated with anti-rust processing.
