Tri-Circle® Barrel Design

The science behind the Lauren Liner’s design focuses on a Tri-Circle® barrel that provides full teat massage to prevent teat duct congestion, while reducing any unneeded pressure on the teat ends. This produces higher peak milk flow and maintains udder health.

The Tri-Circle Collapse

The Tri-Circle barrel collapses more evenly under vacuum than other milk liner shapes, providing a gentle milk stroke that provides more contact between the liner and the teat to reduce blood pooling and increase comfort.


The mouthpiece is specifically designed to prevent slippage on the teat, ensuring significantly fewer squawks and fall-offs.
