The milking tube section of a milking inflation includes an elongated stem portion having a claw end portion which has an upper end located above the outer end of a milker claw nipple when installed thereon. The stem portion has a circumferentially extending, generally V-shaped groove at a location near the lower end of a teat cup shell in which the inflation is installed and/or at a location adjacent the upper end of the claw end portion. These grooves are arranged to permit substantial relative bending of portions adjacent each groove without substantial crimping which causes a reduction in the internal cross sectional area of the flow passage extending through the milking tube section. The resulting flexibility facilitates installation of a teat cup assembly on a cow's teat and provides improved teat-hanging characteristics.
