Perfect fit for industrial mixer

Used this coupling for a food grade agitator shaft. The 316 steel holds up well against cleaning chemicals. Machining was precise.

Great for chemical environment

Using 316 grade in our plant. No signs of rust after months of exposure to mild acids.

Excellent reduction adapter

Handled the torque well without slipping. Great solution for adapting motor shafts to smaller rods.
