S coupler series KK employs a unique connection method. A slim body design and large effective area are achieved with a construction that does not use steel balls or valve springs and therefore does not restrict the flow path. Together with a reduction of the body size, pressing parts and resin parts are used to achieve an overall weight reduction.
