A dairy inflation includes a barrel portion connected to a milk tube portion for extracting milk from a teat of an animal. The barrel portion includes an axial passage defined by a wall, the wall having an exterior surface defining an outer periphery having a substantially circular shape. The wall further includes an interior surface defining an inner periphery having a substantially elliptical shape. The elliptical inner periphery includes a major axis and a minor axis, and the disposition of the elliptical inner periphery within the circular outer periphery creates reduced-thickness regions on opposing sides of the wall along the major axis. The reduced-thickness regions allow a controlled collapse of the barrel portion during milking operations.
