4' ALUM COUPLER X FEM THREADS, PART D

This is a 4-inch aluminum cam and groove (Camlock) Type D coupler with female NPT threads. It is typically used to quickly connect and disconnect hoses or pipes in liquid transfer applications such as on tank trucks, in agriculture, or industrial fluid handling. Replacement is needed when the aluminum body becomes damaged, corroded, or the cam arms no longer maintain a tight seal.
