Single ball rubber joint is mainly used for pipeline to reduce vibration, reduce noise, good elasticity and easy to use. Single ball rubber joint is also called rubber soft joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a pipeline joint with high elasticity, high air tightness, medium resistance and weather resistance. This product takes advantage of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of rubber. It is made of high-strength and hot and cold stable polyester cord fabric, which is compounded with it and then vulcanized by high-pressure and high-temperature mold. Single ball rubber joint is composed of fabric-reinforced rubber parts and flat flexible joints. It is a pipeline joint with high elasticity, high air tightness, medium resistance and weather resistance.
