Rubber Expansion Joints Manufacturers provide a full range of high-quality rubber expansion joints and duckbill check valves from DN50 to DN3000, designed for reliable performance in water supply, wastewater, irrigation, and industrial pipeline systems. Our rubber expansion joints are engineered to absorb vibration, reduce noise, and compensate for thermal movement or misalignment, ensuring long-term protection of pumps and piping equipment. The duckbill check valve offers a simple, maintenance-free solution for backflow prevention, using its flexible rubber "duckbill" outlet to allow forward flow under pressure and instantly seal when flow reverses.
