Specially developed, resilient, non-cold-flow neoprene biscuits are responsible for the flexibility of the MORFLEX^® coupling. Relative movement between shafts is confined to the controlled displacement of the neoprene. Preloading the biscuits in assembly permits them to allow considerable deflection, even with light load. The shape of the neoprene biscuit has been carefully designed for uniform stress and deflection. This is an important operational advantage and contributes greatly to the life of the coupling. MORFLEX couplings can be used in ambient temperatures ranging from 0°F to 200°F.

The MORFLEX coupling also has a universal driveshaft series for greater shaft separations with a slip joint construction. This allows universal action to accommodate angular or parallel misalignment. The shaft members are full spline connections, and slide freely under load.
