Consisting of vacuum pump (with pressure gauge), milk jars, inlet lids, teat cups, milking lines, and cleaning brushes, the Henry Goat Milking Kit is designed to make the milking job easy on both hands and back: the hands because milking is done via vacuum pump, and the back because one is not confined to a single position but can move around. Also, the vacuum pump's gauge and release valve allow for raising/lowering the pressure, which helps prevent teat or udder damage which can happen when pressure is constant. Because it's a closed system (i.e., milk travels through the lines from teat to sealed container), the milk stays clean and pure. Clean up involves simply wiping off the pump, washing out the milking lines with a tubing brush, and washing/drying inlet lid and teat cup. (Carrying bag optional.)
