An actuator and hose assembly is provided which allows conveyance of pressurized fluid from a conventional aerosol container to a receiver and which allows precise delivery of only that portion of the container contents needed while allowing the balance of the fluid in the container to be saved for future use. The preferred actuator and hose assembly includes a fluid conveying hose having a conventional fitting at one end thereof for fluidically coupling one end of the hose with a receiver of the fluid, and an actuator sub-assembly coupled with the other end of the hose. The sub-assembly includes an actuator collar configured for friction coupling with the seam ring of the aerosol container, a selectively manually shiftable, upwardly biased, actuator element coupled coaxially within the collar and presenting a stem-engaging shoulder configured to abuttingly engage the end of the container stem in order to shift the stem downwardly, and an enclosed fluid departure channel defined in the actuator element for directing the fluid escaping through the stem into the other end of the hose with the shoulder providing a fluid seal between the stem and element.
