Hydraulic Quick Connect CouplingsHydraulic Quick Connect Couplings are high pressure, no-spill, coupling sets offered in a variety of common interchanges, sizes, and materials to meet your project requirements. They feature a valved coupler and nipple that allow for the safe and easy disconnection of hose that has fluid remaining in the line. Flow automatically begins when coupling halves are engaged. Newly redesigned sealing systems and internals offer improved flow and easy connection under pressure (some styles).

Also available without the valve on one or both sides for economic options suitable for many applications where flow is turned off by a separate valve or where shut off is not required on both coupling halves.
