Safety Modification of Cam-and-Groove Hose Coupling

A modification has been made in the mating halves of a cam-and- groove hose coupling to prevent rapid separation of the halves in the event that the cam levers are released while the fluid in the hose is pressurized. This modification can be duplicated on almost any commercially available cam-and- groove hose-coupling halves and does not interfere with most vendors’ locks that prevent accidental actuation of the cam levers.
