The MultiFaster Quick-Connect Coupling allows one to connect (and/or release) several hydraulic, electrical, and/or pneumatic lines simultaneously with the pull of the coupling unit handle. In addition to reducing the time it takes to carry out this task, other benefits of the MultiFaster system are: reduced risk of line misalignment, polyurethane seals that protect against extrusion and wear, a safety locking device that prevents accidental disconnection, a protective dust cap, flat surface on fixed block that facilitates cleaning, connectable/disconnectable under pressure, and mountable on existing systems.
