Double Ball Rubber Joint

Double ball rubber joint, referred to as rubber joint, is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The double-ball rubber joint is generally composed of an inner rubber layer, a fabric reinforcement layer (the reinforcement layer has multiple layers of squeegee nylon cord fabric), a middle rubber layer, an outer rubber layer, and a reinforced metal ring or steel wire loop at the end.

Double ball rubber joint is called rubber joint for short. It is a kind of pipeline joint which is high-flexibility,high-gas tightness，resistance to medium and climate. Double ball rubber joint is usually composed of inner rubber layer,fabric reinforcement layer(reinforcement layer have multilayer frictioning nylon cord fabric),middle rubber layer,outer rubber layer,top reinforce metal ring or bead ring. After high pressure, high temperature vulcanization and become. It can reduce the vibration and noise of pipeline.It can also compensate for the Thermal expansion and  cold contraction caused by temperature changed.
