Munro Heavy-Duty Flexible Coupling M7707


Munro Heavy-Duty Flexible Coupling M7707

Made to USA standards, to easily interchange with other major manufacturers, the Munro flexible coupling is ideal for use in countless piping applications where misalignment might be present and a heavy duty coupling is needed. The M7707 can accommodate vibration, thermal stress and moderate seismic activity. This tried and true coupling offers pressure ratings to 750 PSI, depending on pipe size and wall thickness.
