The AJ520 rigid joint is designed with a diagonal slide method to provide a solid connection. It is is easy to join high-pressure pipes.
The Model AJ520 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.
AJ520 couplings should always be installed so that the coupling bolt pads make metal to metal contact
