Organ tube is a term used to describe a type of PIPE that is made from organic material. It is often used in plumbing and irrigation systems, as well as for other applications where a durable, flexible PIPE is needed. The term 'organ tube' is derived from the Latin word organum, which means 'INSTRUMENT'. Organ tubes are typically made from materials such as bamboo, reeds, or other plant fibers, and are often used in areas where metal pipes are not suitable.
