The first dairy tubing that combines a smooth sanitary interior surface with a durable, flexible rubber exterior; developed with milk quality in mind. Thin inner layer of Thermoplastic Vulcanizate (special plastic material with rubber-like properties) maintains a sanitary surface over time. Inner surface will not crack, pit or degrade, thereby deterring bacterial growth. High chemical resistance prohibits the migration of rubber chemicals into the milk, resulting in low extractables. Long-lasting, rubber exterior provides excellent ozone resistance. Will clean better and maintain milk purity better than traditional rubber tubing. Even suitable for medical applications. 5/8" I.D. or 3/4" I.D. Sold per 65 ft.
