U-S-Pipe - Model NXT Series -Ductile Iron Pipe
NXT is U.S. Pipe`s next generation `push on` type pipe. The advanced design utilizes a lip type seal gasket cross section which allows for lower insertion forces and greater joint deflection when compared to similar push on joint designs. Features incorporated into the joint also allow the gasket to resist being unseated or rolled during joint assembly and the sealing ability increases with increased system pressures.
