Many milk tubes and connectors are used for a multitude of models and accessories. The length of the milk tube is about preference. Many customers who own a stainless steel Thermal Milk Container or Cool Control tend to prefer the 120mm milk tubes because the milk is extracted from a shorter distance. The 360mm milk tube will work efficiently for these accessories; however, the shorter the extraction distance, the more uniform the pressure is. Generally, the 360mm milk tubes are for customers who insert the milk tube directly into a carton, bottle or glass to extract the milk.
