Ordinary rubber gasket for the temperature below 120 ℃ occasions; asbestos rubber gasket is suitable for water vapor temperature below 450 ℃, the oil temperature below 350 ℃, the pressure is less than 5MPa of the occasion, for the general corrosive Medium, the most commonly used is acid asbestos board. A gasket is a ring made of a material that produces plastic deformation and has a certain strength.
