The material belongs to polar rubber, good sealing, light weight, easy installation and maintenance, long service life, which can greatly reduce the vibration and noise of pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and contraction and different centrality of various pipelines. But avoid contact with sharp metal instruments, so as not to pierce the sphere.
It can be made into various varieties of acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, heat-resistant, etc. according to different materials, which can adapt to various media and environments, and more effectively prevent the erosion of corrosive media on the inner wall of rubber joints and improve the service life.

Because of its good comprehensive performance, it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire-fighting, electric power and other infrastructure.
