MILKING MACHINE SPARE PARTS

Melasty Liners (27mm) — The Flexible Rubber Sleeve That Contacts the Teat Directly

  • The flexible rubber inner liner that sits inside the rigid teat cup shell and makes direct contact with the teat during milking
  • 27mm refers to the liner's bore diameter — sizing needs to match your herd's teat size for both milking effectiveness and animal comfort
  • One of the most frequently replaced parts on any actively used milking machine, since it's the component under the most repeated mechanical stress

Of every part in the milking cluster, the liner is the one actually touching the animal — it's the flexible rubber sleeve that sits inside the rigid Teat Shell and does the physical work of opening and closing around the teat in rhythm with the pulsation cycle. Because it's flexing thousands of times per session, every session, it's also the component that wears out fastest across the entire system, and a worn liner affects both milking efficiency and udder health directly, since it's in constant physical contact with the animal.

The 27mm sizing refers to the liner's bore diameter, and getting this right for your herd's actual teat size matters — a liner that's too tight or too loose doesn't grip and massage the teat correctly, which can affect both milk-out completeness and, over time, teat condition. Because liners wear with use regardless of how well the rest of the machine is maintained, most dairy operations replace them on a fixed schedule (by milking count or time elapsed) as standard practice, rather than waiting for a visible problem to appear.

The liner is the flexible rubber part that directly contacts the teat and does the physical milking action; the Teat Shell is the rigid outer casing the liner sits inside. They work together but wear at very different rates — liners need far more frequent replacement.

Bore diameter should match your animals' actual teat size — too tight or too loose affects both milking efficiency and teat health. Tell us your breed and typical teat size and we can confirm whether 27mm is right or whether a different size suits your herd better.

Liners wear with a fixed amount of use regardless of visible damage, so most dairy operations replace them on a set schedule — by milking count or elapsed time — rather than waiting for a visible problem. Ask us for a recommended interval based on your daily milking volume.

It refers to the specific rubber compound/material used in this liner — ask us for the technical details if you'd like to compare it against other liner materials.
