Rubber Gasket

Rubber gasket is suitable for a wide range of needs of gasket, it is vulcanized by polymer, and a variety of additives, add filler, pigment constitute a full rubber, has good scalability, as long as very low consolidation force can play an effective sealing effect in low temperature and low pressure occasions, well and from the flange face removal will not split. Good sealing effect can also be achieved on uneven and damaged flange surface. Because of the strong expansion permeability of provincial military glue, it can form a very effective sealing effect on the passage of gas and fluid resistance.
