ISO 5675 Hydraulic Quick Coupling

The ISO 5675 series hydraulic quick coupling features a rugged steel ball valving architecture designed for reliable fluid isolation in medium-to-high pressure oil pump circuits and agricultural machinery. Constructed from high-tensile carbon steel and treated with a protective yellow zinc plating, this double shut-off coupler automatically seals both the plug and socket paths instantly upon disconnection. Its standard ball-lock sleeve mechanism facilitates quick and dependable connect/disconnect cycles, making it a highly durable solution for demanding mobile equipment and industrial hydraulic lines.
