An inflation for an automatic milking machine is molded as an integral unit from an elastomeric material. The inflation is formed to have an elongate, hollow barrel. The barrel has a substantially square cross-sectional shape and terminates in open upper and lower ends. A substantially cylindrical head is molded integrally to the upper end of the barrel. The head has a substantially cylindrical side wall. A diaphragm-like mouthpart is positioned across the otherwise open, upper end of the cylindrical side wall, with the mouthpart having a central opening that is adapted to accommodate the teat of an animal to be milked. A transition section is molded in the head so as to connect the upper end of the barrel with an inner surface of the side wall to form an internal, mouthpiece chamber between the transition section and the mouthpart. The transition section has an outwardly curved surface that curves from the upper end of the barrel to an inner surface of the side wall in a smooth curve having a radius of about 0.430 inch to about 0.445 inch./!
