Easy Installation & Alignment Lightweight and flexible, allowing for quick installation and easy pipe misalignment correction. Reduces labor and installation costs. Pressure & Vacuum Resistance Designed to withstand both positive and negative (vacuum) pressures without collapsing. Enhances reliability in critical piping systems. Protection Against Water Hammer Acts as a cushion to reduce impact from water hammer and pressure surges. Minimizes wear and potential system failure. Extended Equipment Life By reducing mechanical stress and vibration, rubber expansion joints extend the life of pumps, valves, and piping systems.
