Figure 716
Flexible Reducing Couplings Tech Data Sheet: G120
The GRINNELL Figure 716 Flexible Reducing Coupling allows for a direct transition between two different pipe sizes and replaces two couplings and a reducing fitting. It is capable of pressures up to 34.5 Bar (500 psi) depending on pipe size and wall thickness. A flexible reducing coupling
is not recommended for low-temperature applications.

* Maximum available gap between pipe ends. Minimum gap = 0.
† Maximum pressure and end load are total from all loads based on standard weight steel pipe. Pressure ratings and end loads may differ on other pipe
materials and/or wall thickness. Contact GRINNELL Products for details.
‡ Max end gap and deflection is for cut grooved standard weight pipe. Values for roll grooved pipe will be half that of cut grooved. For information on alternative sizes, contact a GRINNELL Sales Representative.
See page 17 for coupling specifications and pages 116 - 127 for gasket information.
For instructions on part numbers, ordering information, and availability, refer to page 13 or contact a GRINNELL Sales Representative.
