Round Bore Liners
All Conewango Round Bore Liners are manufactured from our time-tested natural rubber formulations.
No Break-in Period
100% synthetic-rubber liners are often stiff and uncomfortable to the cow after a liner change, causing flare-ups and hard quarters. Using Conewango round bore liners will completely eliminate this.

Improved Milk Out
Leaving milk in the udder adds up fast. Improved milk outs will not only increase yields but also lead to healthy udders and higher milk quality.

Less Slippage
As many as 20% of new cases of mastitis are caused by liner slippage. Reduce slippage and you reduce mastitis and improve udder health.

Wide Range
There is a Conewango liner to fit all shells commonly used in the USA. All Conewango liners can be vented upon request.
