Abstract: A tapping fitting for a pipe, preferably a plastic pipe, includes a rotatable blade assembly threaded within a sleeve non-rotatably received within a housing such that rotation of the blade assembly causes it to cut a cylindrical slug from the pipe to which the housing is attached. The opposite faces of the sleeve are exposed to the fluid pressure within the pipe thereby producing a balance of forces substantially eliminating transverse creep. In addition, the attaching section of the fitting is formed with a bore which is engageable by a sealing ring received around the rotatable blade assembly and which is of sufficient length to accommodate any axial creep, thereby enabling the blade assembly also to serve as a valve.

Abstract: A water delivery assembly for attachment to a pressurized water supply pipe particularly useful for supplying drinking water to poultry, includes a housing having an elongated flow passageway between its inlet and outlet restricting the water flow through the outlet, and thereby permitting the assembly to be used with water supply pipes supplying water at a relatively high pressure.
