The MIPT Unions are designed for easy access to the PerformancePro
Artesian pumps. The PerformancePro Artesian pumps require two
MIPT Unions (one on the suction side, and one on the return side).
They are threaded on one side and slip-fit on the other. Using
MIPT Unions makes life a lot easier if you ever have to remove your
pump from the system for any reason.
