The rubber washer is a sealing component for sealing and cushion between two stationary contact surfaces, with various shapes and varieties, made by molding or punching. It features oil, acid and alkali resistance, cold and heat resistance, pressure resistance, strong interchangeability, convenient assembly and disassembly and other properties; a certain elasticity to make the contact surfaces well fit. It is widely used in hydraulic, pneumatic, instruments, pipeline, valve and other sealing occasions.
