Key benefits

- Enhanced durability: Independently trialed and proven to last up to 8,000 milkings – that’s up to three times more milkings than a traditional liner
- Improved cow comfort: Transitional barrel reduces teat ringing and congestion for greater cow comfort
- Perfect for large herds: Designed for high-capacity dairy operations with reliable, efficient performance
- Optimized milking performance: Faster milking with reduced teat stress, improved let down, and better milk flow
- Cost-effective: Extended-service silicone reduces the need for frequent liner changes, saving time and lowering operating costs

Innovative design features
- Hygienic silicone: Resists milk fat absorption, bacteria growth, and oxidation for long-lasting performance
- Transitional barrel design: Round-to-square barrel minimizes mouthpiece vacuum for greater cow comfort. It mimics the internal geometry of a calf’s mouth and tongue, creating a gentle massaging effect for improved milk let down and flow
- Pre-loaded shell: The liner comes pre-loaded in a lightweight, recyclable, single-use shell, making installation and liner changes quicker and more efficient, saving time
- Patented square hackle: The shell features alignment indicators and a square hackle design that creates a strong seal that keeps pulsation lines clean and prevents twisting
- Locking head design: Eliminates twisting and prevents head of liner from pulling away from shell
- Vented design: Domed vent surface and inverted conical hole prevents plugged vents
- Heavy duty bumper rings: Allow for radial expansion and enhanced durability
- Vented and non-vented options: Customizable to suit different milking systems and herd needs
