The present invention provides in combination with a ball-valve, an improvement comprising a threadless metallic fitting that incorporates both a male portion and a female portion formed as an integral unitary structure extending from at least one end wall of a housing portion of the ball-valve. The threadless metallic fitting includes a sleeve portion having a female interior surface adapted for receiving one of a tube and a pipe section therein and a male exterior surface having at least two distinct cylindrical sections. There is also a driver member having at least two distinct cylindrical sections for engaging the male exterior surface of the sleeve portion for deforming the sleeve portion and concurrently deforming such one of such tube and pipe section engaged within the sleeve portion when the driver member is forced longitudinally along the male exterior surface of the sleeve portion so as to effect an air tight seal between the pipe section and the female interior surface of the fitting.
