Milking speed is
uninhibited, and
airflow is maintained
up the side channels

fully collapsed state.

The three channels

allow for

maximum flow of

evacuated milk,

resulting in high speed and good
teat end health

Much more than “fair and square”

Square-barrelled Evolution X2 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.
