1. A milking teat liner for use with a teat cup assembly including a rigid shell as part of the teat cup assembly comprising: a head having a mouth opening and a generally cylindrical skirt having an inner surface and an outer surface said skirt depending downwardly from said mouth opening, a barrel depending downwardly from said head, said barrel extending axially along an axis for receiving a teat inserted axially thereinto through said mouth opening of said head, said barrel having a barrel wall wherein said barrel wall acts with said inner surface of said skirt to define a circular slot adapted to frictionally receive the shell; wherein said barrel wall has a reinforced sidewall regions that protrudes on an external surface of the liner to frictionally receive the shell; wherein a percentage of a total sidewall that is reinforced is substantially similar to a percentage of the total sidewall that is unreinforced; a scalloped skirt extension distal to said mouth opening to form a suction chamber between said skirt and said shell to increase friction between the skirt and the shell, to prevent twisting of the liner within the shell during use, and to reduce contaminants from entering the shell; wherein the suction chamber is a ring-shaped concave portion at an end of the skirt distal to said mouth; wherein said concave portion is on an inner surface of said skirt adjacent the shell, and a short milk tube depending downwardly from said barrel.
