0250037-556 Sullair OEM Drive Coupler

The 0250037-556 Sullair OEM Drive Coupler is an OEM coupling for Sullair portable air compressors. This elastomeric coupling provides the flexible engine-to-airend connection in select Sullair portable models, delivering torsional damping and vibration isolation in continuous-duty compressor service.

Sullair’s portable compressor fleet spans compact jobsite units to large production machines, and each model uses a coupling matched to its specific torque and vibration requirements. The 0250037-556 is configured for its target Sullair models with the correct elastomer specification and mounting configuration.

This is a direct factory replacement. During installation, clean shaft surfaces, inspect hub condition, and follow Sullair’s alignment procedure. Verify vibration levels after startup.
