128387-412 Quincy OEM Coupling Element

The 128387-412 Quincy OEM Coupling Element is a replacement component for the drive coupling in Quincy Compressor systems. This element serves as the flexible insert in the coupling assembly, providing torsional damping between the motor and airend.

Quincy’s 128387 coupling family serves multiple compressor models. Using the correct part number ensures the element’s stiffness and damping characteristics match the compressor’s drivetrain requirements.

Element-only replacement is appropriate when the coupling hubs remain in good condition. Inspect hubs for wear before installing the new element. Clean mating surfaces, verify alignment, and run the compressor through its normal operating cycle to confirm smooth performance before returning to production service.
