A hydraulic quick coupling, also known as a quick disconnect, is a mechanical device used to quickly and easily connect or disconnect hydraulic lines without the need for tools. It allows hydraulic fluid to flow between different components, such as pumps, hoses, and cylinders, by creating a leak-proof connection.
Quick couplings typically consist of two parts: the male plug and the female socket. When these two parts are connected, they allow fluid to flow through the system. When disconnected, valves within the coupling close automatically to prevent fluid leakage.
