Munro Reducing Coupling M7706


Munro Reducing Coupling M7706
The Munro reducing coupling is ideal for transitioning from one size piping to another. The M7706 is a flexible coupling and can accommodate vibration, thermal stress and moderate seismic activity. This tried and true coupling offers pressure ratings to 500 PSI, depending on pipe size and wall thickness.

Materials
