  • Coupling part
    Patent number: 5197770
    Abstract: The coupler part allows for joining of a hydraulic line to a hydraulic component such as a hydraulic cylinder. The coupler has an outer and inner element. Both elements are sleeve-like in construction. The outer element is attached to the hydraulic component while the inner element is connected to the hose. A slit ring or spring fingers are used to allow the inner element to easily couple with the outer element but prevent the inner element from uncoupling from the outer element except by disassembling the whole coupler unit.
