Abstract: An adapter is disclosed for a can filling machine permitting the machine to be utilized to fill aerosol cans having a "female" type discharge valve. The adapter includes a fill head which is threadably attached to the paint reservoir of the can filling machine permitting the injecting piston of the can filling machine to be received within the working bore of the fill head. A valve engaging member is threadably attached to one end of the fill head and a spring therein biases a ball against a passageway in the bottom of the working bore. The other end of the valve engaging member has a "male" tip formed thereon which is received within the "female" type discharge valve in the aerosol can and depresses a valve body therein. Depression of the valve body within the "female" type discharge valve by the "male" tip of the valve engaging member permits paint within the working bore of the fill head to be injected into the aerosol can.
