All Conewango square liners are manufactured from our time tested and natural rubber formulations. Using Conewango square liners
will improve teat end condition and as a result reduce mastitis. Dairymen using our square liner have experienced a significant
reduction in hyperkeratosis versus round bore liners. The design of a square liner allows for improved milk flow and a better milk
out. Square liners will milk out faster and more completely than triangular liners due to the unique combination of barrel collapse
design and Conewango's natural rubber formulation. Using Conewango liners will completely eliminate problems associated with 100%
synthetic rubber liners which are often stiff and uncomfortable to the cow after a liner change, causing flare-ups and hard
quarters. Replaces IBA Pro Square D, Pro Square D Px. DeLaval square, narrow bore, extended life.
