Hex Bushing 1/2" MNPT x 3/8" FNPT

This galvanised malleable-iron hex bushing reduces a half-inch male NPT thread to a three-eighths female NPT thread. It is rated for Class 150 service and carries the Zoro Select brand. The fitting is new and intended for plumbing installations that require a secure, corrosion-resistant transition between pipe sizes.

For installers reducing NPT pipe threads

Plumbers and maintenance technicians who need a durable, galvanised reducer for water, air or oil lines will find this bushing suitable. It is not intended for applications that exceed the Class 150 pressure rating or for systems requiring stainless steel or brass construction. Buyers who need a different thread combination or a higher pressure class should look at alternative fittings.

Class 150 capacity with standard NPT engagement

The bushing comfortably handles the pressures associated with Class 150 piping systems in typical residential and light-commercial use. Its malleable iron body provides mechanical strength for threaded connections, while the galvanised coating resists rust in damp environments. It runs out of headroom in high-pressure hydraulic circuits or in chemically aggressive fluids that demand alloy materials.

Questions about this item

What size male thread must the existing pipe have for this 1/2" MNPT bushing to connect?

The bushing has a 1/2 inch male NPT thread, so the pipe or fitting you are joining it to needs a matching 1/2 inch female NPT opening.

Will the galvanized Class 150 rating handle the same pressure as the older black iron fittings I am keeping?

Yes, the Class 150 malleable iron body is rated for the same 150 psi working pressure as standard Class 150 black iron fittings.

How can I confirm the 3/8" FNPT outlet is threaded correctly after I install the bushing?

Thread a known-good 3/8 inch male NPT fitting into the outlet; it should engage smoothly for several turns and seal without cross-threading.
