Abstract
A flexible formed pre-curved milk tube (50) extends outwardly from a milking claw inlet (26) and naturally curves upwardly to a teat cup (20), minimizing stress otherwise occurring in a straight milking tube (40), such that the pre-curved tube (50) maintains increased clearance (52) between the pre-curved tube and the claw inlet opening (44) to maximize the inner cross sectional area of the tube and create less restriction to flow as compared to the reduced clearance (46) caused by stressing a straight tube (40) to a curved connected condition. Rotation of the pre-curved tube (50) from the unstressed position to a downward non-milking position provides a greater range of motion than a straight tube (40), which greater range of motion provides a better shut-off seal.
