Barbed Union

Barbed unions are made of food grade Polypropylene, which can be sterilized via gamma radiation. This type of tube fitting is available in a variety of standard sizes from 1/6″ to 11/32″ for low pressure plumbing applications with various types of hoses. The barbs grip the inside of the flexible tube to create a seal and easily connect fluid paths without the use of tools.
