Japanese standard quick couplings are compatible with Japanese design specifications and are made of copper. They are generally divided into open flow and with valve types, and can withstand a pressure of 15Bar. The male water nipple usually uses the PT thread standard of the British imperial system. Quick couplings are mainly used for the circulation of cooling water systems in plastic molding and die casting molds. The sealing ring uses a fluorine rubber ring, and the highest temperature can reach 200°C.
