ISO 7241-A Hydraulic Quick Coupling

The ISO 7241-A series hydraulic quick coupling is a globally standardized, double shut-off fluid connector designed for dependable interchangeability across diverse agricultural and industrial oil lines. Constructed from high-tensile carbon steel and protected by a clean white zinc plating, it incorporates spring-loaded poppet valves in both the socket and the plug halves. This structural layout provides automatic and instantaneous shut-off when disconnected, successfully sealing the media and eliminating system pressure loss. Its classic ball-locking sleeve mechanism enables robust push-to-connect field operations under demanding medium-to-high pressure workflows.
