Used for washing the measuring tube on milk tanks
From the manufacturer: Transflow® Raw Milk tubing is specially formulated to reduce the risks that can occur with the use of rubber tubings. Many regulatory sanitarians throughout the world recognize Transflow® as the preferred tubing for raw milk transfer. Long lasting Transflow® tubing is extremely flexible and installs quickly and easily around stantions and milk handling equipment. It resists embrittlement and cracking from oxidation that often shortens the service life of other tubing.
