Good value for industrial use

We replaced several old couplings with these. They handle minor misalignments well. The only reason for 4 stars is that the documentation could be more detailed regarding torque limits.

Great replacement part

Needed a specific GB standard coupling for a retrofit project. This unit worked flawlessly. The high toughness claim seems accurate based on our stress tests.
