HQ Series Couplings are designed to be used in dirty environments and where oil loss or air inclusion cannot be tolerated on connection or disconnection.
The flat face feature allows the operator to clean the coupling surfaces to prevent contamination from entering the system. Typical applications include skid steer attachments, excavator hammer circuits, hydraulic hand tools and breakers, mobile equipment, general industrial, mining and agricultural. Fully compliant with ISO 16028 for interchangeability, dimensions and performance.
