Abstract
A method and apparatus for an improved rotatable safety cam lock fitting with an air vent, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. Rotation of the female portion is accomplished by placing a connecting collar on the rear of the female end portion so that the female portion rotates about the connecting collar. The safety lock mechanism operates by placing opposing notches in the end of the male portion so that when the cam levers are opened the male and female portions of the cam lock fitting initially only slightly separate allowing the operator to quickly reclose the cam lock fitting if it contains pressurized material. The rotating female portion easily aligns the cam lobes of the cam lever with the notches on the male coupling so that the male and female portions can be separated.
