According to different types of rubber soft connection can be made into general class, oil-resistant, ozone-resistant, wear-resistant, acid and alkali-resistant, resistant to chemical corrosion of the special and heat-resistant more than 80 degrees. This product imported foreign advanced production process, the production process of the inner layer by high pressure, nylon cord fabric and rubber layer to get a better combination than the ordinary flexure rubber joint of higher pressure, better quality. Features are a blend of the inner rubber layer, smooth and seamless, the label using vulcanization process, and the product together. Special cold water, hot water, Compressed air and natural gas for rubber joint. It solves the problem of burst and damage of pipeline connecting equipment caused by hot expansion and cold contraction, with special design, novel structure and good sealing performance, the utility model effectively improves the service cycle of the pipeline and the protection of the equipment.
