PVC Pressure Barrel Union

Barrel Union (CAT No.22)

A PVC Pressure Barrel Union is used to break the line and allow access for maintenance. The locking nut can be unscrewed to allow a section of pipe or a fitting to be removed. Often a barrel union is used in front of a check valve or a pump to isolate it and to have the ability to break the line. Commonly used in irrigation or pool applications.
