Shurjoint Z07N Heavy Duty Ductile Iron Angle-Pad Rigid Coupling
The Shurjoint Model Z07N is an angle-pad design rigid coupling for general piping applications where rigidity is required including valve connections, mechanical rooms, fire mains and long straight runs. The angle-pad design allows the coupling housings to slide along the bolt pads when tightened. The result is an offset clamping action which provides a rigid joint that resists flexural and torsional loads. Model Z07N is a two-segment coupling which is available in sizes 14″ – 24″. Support and hanging requirements correspond to ANSI B31.1, B31.9 and NFPA 13. The Shurjoint Z07N is available with a standard “C” shaped or GapSeal gasket in a variety grades to meet your specific service requirements.
