Specifically designed for the low vacuum, high volume milking. Fully welded nipplecannot break off like cheaper shells. The dual size barrel of the stainless steel shell serves two purposes. The wide upper barrel allows the shell to adapt to various size teats. The narrow lower barrel reduces air displacement between the shell and the inflation. The less air displacement the more accurate and consistent the inflation action. The narrow lower barrel also helps prevent inflation creep. The ribbed rim of the shell keeps inflations from twisting around during milking and wash up. The shell also has a ribbed edge to prevent inflations from twisting.
