(Also known as Hydraulic Quick Coupling / Quick-Connect Fitting / Hydraulic Quick Disconnect)
A Hydraulic Coupler is a precision-engineered connector that allows hydraulic hoses and tools to be quickly connected or disconnected from a hydraulic system without fluid leakage or air ingress. It is commonly used in hydraulic torque wrenches, cylinders, pumps, jacks, and construction equipment to enable fast, safe, and clean setup or changeover of hydraulic lines. High-quality couplers are designed to withstand high operating pressures (up to 700 bar / 10,000 psi or more) and are built for durability, corrosion resistance, and minimal pressure drop.
