Threaded connection flexible rubber joint, also known as air condition flexible hose, it is a kind of flexible rubber joints, belongs to flexible connectors of metal pipelines. Threaded connection rubber joint composed of inner rubber layer, chinlon tyre fabrics enhancement layer and outer rubber layer, then by molding vulcanization and combine with screw thread. Inner rubber layer directly bear abrasion and corrosion of medium delivered; outer rubber layer protect rubber joint from being damaged and corroded by external environmental; enhancement layer is the pressure-bearing layer, giving rubber joint strength and stiffness, the working pressure of rubber joint depends on material and structure of enhancement layer. General rubber joint’s inner and outer rubber layer use NR, SBR or BR; oil resistant rubber joint use NBR; acid-base resistant, high temperature resistant rubber joint use EPDM. Thread types includes internal thread and external thread, internal thread is the commonly used thread connection method. For thread material, Malleable fitting is in common use, 304 or 316 stainless steel is available in special condition. Thread connection rubber joint has high elasticity, high gas tightness, medium resistant and weather resistant, widely used in water supply, steam supply, oil supply, air condition, draught fan and other pipe fittings.
