The R1-EX liner features a “Double Seal” mouthpiece that will accommodate a wide range of teat sizes without being constrictive to milk flow on larger teats. It has a smaller bore than the DK-1X and a thinner liner barrel wall. R1-EX is well suited for dairies with low vacuum level setting. These liners fit both Flo-Star claws and Visi-Claws. They are available with or without patented Jet-Vent air vents.
