This document details the design, materials and dimensions for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam. The couplings are capable of operating the pressure range - 0,8 bar to !16" bar working pressure in a working temperature range of - 20 °C up to + 65 °C. WARNING — Line pressure shall be reduced before disconnection.
