Drive performance in the milking parlor with the RST-Driver, engineered for high speed, low slip, and easy use. This innovative liner features a transitional barrel shape to minimize mouthpiece vacuum and non-round advantages for optimal teat-end health.
Vented models move milk away from the teat end with a redesigned clog-free vent and new vent seat for improved retention. Crafted from high-performance rubber and used with a custom-molded nylon shell, the RST-Driver is lightweight and extremely durable, ensuring a good fit and secure seal.
Its unique barrel geometry mimics the natural shape and motion of a suckling calf, enhancing cow comfort and milking performance. Extensively tested and proven, the RST-Driver outperforms leading competitive liners, delivering uncompromised performance for every milking.
