Code of rubber

Rubber gaskets are widely used in very large scope and composed different kinds of materials to become synthetic rubber. It has excellent compressibility and recovery. It plays good function under the work situation with lowest bolt-load; it wont split after removed from the flange. Rubber gaskets can keep good sealing function even though the flange is damaged and not plain and smooth. As rubber has the property of special expand and permeate resistance, it plays the effectiveness sealing role to resist gas and liquids to through and formation
