It features a female camlock (coupler) on the 3-inch side and a male adapter on the 4-inch side, making it easy to join a 3-inch hose to a 4-inch tank fitting or vice versa. Common applications include fuel delivery trucks, chemical trailers, and industrial fluid handling where frequent disconnection is needed. Replacement is typically required when the cam arms become stiff or worn, the gasket fails, or the aluminum body cracks from corrosion or impact.
