The rationale behind the design of the Carrera Greenmaster hose connector was to avoid the shortcomings of current screw connections. Thus, the patented product solution was equipped with an integrated clamp screw and a water stop. The clamp connection is non-drip and tight. When opened, the jaws widen so that the hose can easily be inserted. The operating elements are easy to grip and can even be used comfortably with wet hands.
