The Hose Shank Coupler allows controlled oil flow connections during hydraulic testing activities involving pumps, motors, and transmissions. The coupler helps create temporary hydraulic paths that allow test procedures to proceed without permanent system changes. It supports safe oil transfer between test equipment and hydraulic components while maintaining stable flow conditions. Enabling quick connection and disconnection supports consistent test results by keeping hydraulic flow controlled and uninterrupted during evaluation tasks.Attributes:• Prevents oil leakage during connection and disconnection.• Helps maintain clean oil transfer during testing operations.• Allows quick connection and disconnection during testing cycles.Applications: The Hose Shank Coupler is located within hydraulic test setups where oil lines connect test equipment to the pump, helping ensure stable and repeatable hydraulic performance evaluation during testing procedures.
