A higher standard in low-slip liners.

Evolution XLO Logo
  • Less squawking

    Round bore liner with reinforced barrel creates a progressive, two-stage collapse for greater vacuum stability.


  • Less ringing and congestion

    Shallow vacuum chamber keeps mouthpiece vacuum low,
    reduces ringing/congestion, improves comfort and speed. 


  • Less twist

    Longer skirt with scalloped extension and locking wedges reduces twisting in 06 style shells.

  • Better unit alignment
    Short milk tube with compression ribs and hinge points
    permits more flexible alignment on a range of cows.


  • High capacity milk tube


  • Long-lasting performance for up to
    2,500 cow milkings

Evo XLO Features

Short milk tube: Wider is better.


  • Large inside diameter promotes higher milk flow with greater vacuum stability.


  • Two notches allow bending in the natural direction of the milking machine.


  • Lengthwise ribs maintain inside diameter without kinking for unrestricted
    milk flow.


  • Better unit alignment on a wide range of cows.


Why do liners slip?

Liner slips or fall-offs during milking have
several causes, including:


  • Vacuum set lower than 11 inches Hg*


  • Blocked air vents


  • Kinking in the short milk tube


  • Poor alignment or uneven weight distribution in cluster

  • Poor liner condition

    * For milking at very low vacuum levels, consider Evolution® X by Conewango


Benefits of low slip:


  • Improved overall cow comfort


  • Reduced kicking and stepping during milking


  • More complete, gentle massage


  • Fewer reattachments and disruptions in milking routine

  • Reduced incidence of new mastitis infections

  • Improved milk flow and yield


Evolution XLO Diagram

A higher standard in milk liners.


  • Variation in barrel wall thickness results in a progressive,
    two-stage, controlled collapse.


  • In first stage, inner walls come together at an engineered collapse
    point while outer walls resist collapse.


  • In second stage, air continues to flow up side channels
    past teat, feeding the vacuum chamber.


  • Controlled collapse provides greater 
    stability with virtually no slippage in 
    field tests at significantly lower vacuum.
