The new Evolution® SST-Driver is unlike any other liner on the market. Made from hygienic silicone, the SST-Driver enhances milking performance, lasts longer, and ultimately improves the dairyman’s bottom line.
Because silicone doesn’t absorb milk fat, it doesn’t harbor harmful bacteria. It also doesn’t oxidize over time. This means that a single SST liner can last for 6,000 milkings – that’s up to three times more milkings than a traditional liner.
Our engineers have created the most effective barrel to hit the market yet. Its square shape milks quickly yet minimizes stress on the cow’s teat. Designed to mimic the internal geometry of a calf’s mouth and tongue, the liner creates a gentle massaging action which simulates natural suckling, resulting in a better let down and milk flow.
The SST-Driver comes pre-loaded with a single use, disposable shell and features alignment indicators along with a square hackle. This design creates a strong seal that keeps pulsation lines clean and prevents twisting, saving installation and change time.
