The VALUE COLLECTION WS-HF-CAM-158 is a Part D cam groove coupling designed for fluid transfer applications requiring a reliable female coupler with FNPT threading. Built from aluminum, this 4-inch coupling handles maximum working pressures up to 400 psi, making it appropriate for a wide range of industrial and trade piping systems. The cam and groove design allows for fast, tool-free connection and disconnection, which reduces downtime during fluid handling operations. Plumbers, pipefitters, and industrial maintenance technicians commonly install this type of fitting in temporary or permanent fluid transfer lines.
This coupling is suited for use in applications where aluminum construction is compatible with the media being transferred. The Part D designation identifies it as a female coupler with FNPT (female national pipe taper) threads, allowing it to mate with a standard male NPT pipe end or adapter. It is commonly used in agricultural, industrial, and general fluid transfer setups where cam groove systems are the standard connection method.
Designed as an OEM-style replacement or new-installation cam groove fitting for 4-inch FNPT threaded pipe systems using the Part D female coupler standard.
Installation should be performed by a qualified plumber or pipefitter familiar with cam groove fitting systems. Shut off all flow and relieve system pressure before connecting or disconnecting the coupling. Verify that the mating male adapter thread type and size match the FNPT thread on this coupler before installation. Inspect cam arms and gasket seating surfaces for damage prior to putting the coupling into service.
