Much more than “fair and square”

Square-barrelled Evolution XL² is fast, effective and smart.


In the dairy industry’s ongoing battle to control hyperkeratosis, there is abundant research available to demonstrate the value of square-barrelled liners.


  • Square barrel design provides controlled collapse and reduces 
    pressure on teat end allowing for less hyperkeratosis.


  • When the square barrel collapses, each side comes to rest against
    its adjacent side, resulting in two points of contact within the liner.


  • Three channels are created – one in the center, one on each end.

  • During massage, all evacuated milk that is still in the liner easily
    drains off through the three channels.

  • Good teat end conditions are maintained thanks to the thorough 
    removal of milk and complete, consistent massaging action.
