Soft rubber joints, known colloquially in a flexible rubber joint, rubber joints, its products are widely used in the water, electricity, chemical industry, watercrafts system, main performance high pressure, good elastic (Angle to the axial and transverse displacement) down, light quality, reduce vibration noise, easy installation, flexible use, easy to conversion maintenance, at the same time has many characteristics, such as acid, alkali resistant, oil resistant. The product can be extended automatically in the process of using against natural weather changes. Its structural material is impregnated nylon cord fabric with high strength and aging resistant polar rubber material. In order to prevent the product in long-term use of natural shrinkage and reduce aging fracture, the use of mesh steel wire for multi-body protection. The so-called teflon lined soft joint is in our common rubber soft joint lined with a layer of fluorine material, is its acid and alkali resistance has been greatly improved, but also his service life has been improved. We have reduced the frequency of replacement parts and saved a lot of costs.
