Zoro Select Malleable Iron Union

The Zoro Select 2WU83 is a Class 150 malleable iron union with 2-1/2 inch female NPT threads on both ends. It joins two pipe sections in plumbing systems where occasional disassembly is required.

Installation notes for FNPT union

Thread sealant or tape on the NPT threads ensures a leak-free joint when the union nut is tightened. Mismatched thread standards or damaged threads are the most common causes of sealing problems.

Class 150 pressure rating and limits

The Class 150 rating provides adequate headroom for typical low-pressure water, air and oil lines at ambient temperature. It is not suited for high-pressure steam or hydraulic circuits that exceed the class rating.
