Rubber flexible connectors, also known as rubber soft joints, flexible rubber joints, and rubber shock absorbers, are primarily composed of a tube-shaped rubber component made up of inner and outer rubber layers, a fabric layer, and a steel wire ring. After being vulcanized into shape at high temperature and pressure, they are assembled with metal flanges. They are widely used in fire protection, chemical industry, pump valves, and other pipeline systems, providing vibration and noise reduction, and absorbing displacement generated during pipeline operation.
