The rubber washer is a sealing part of rubber product, for sealing and cushion function between the two stationary contact surfaces with various shapes and varieties. It features oil resistance, acid and alkali resistance, cold and heat resistance, pressure resistance, easy assembly and disassembly and other properties; has a certain elasticity, not stick to the sealing surface. It is widely used in mechanical, instrument, hydraulic, pneumatic, pipeline and other sealing occasions.
