Square Liners
All Conewango Square Liners are manufactured from our time-tested and natural rubber formulations
Udder Health
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.

Improved Milk Out
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.

No Break-in Period
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 flareups and hard quarters.
