Hex bushing reduces 1-1/2" FNPT to 1/2" FNPT in Class 150 malleable iron

  • Malleable iron construction withstands demanding plumbing applications
  • Class 150 pressure rating handles standard service requirements
  • 1-1/2 inch FNPT to 1/2 inch MNPT adapts mismatched pipe sizes
  • NPT threading ensures reliable seal with compatible fittings
  • Hex design allows secure installation with standard wrenches

Hex Bushing 1-1/2" x 1/2" NPT

This malleable iron hex bushing reduces a 1-1/2 inch female NPT thread to a 1/2 inch female NPT thread. It is rated for Class 150 service and features 11-1/2 and 14 threads per inch respectively. The fitting suits plumbing systems requiring a durable, threaded transition between two different pipe sizes.

Suited for threaded pipe reduction.

Installers joining threaded iron or steel pipe of dissimilar diameters will find this bushing appropriate. It is not designed for compression, push-fit or flanged pipe ends. Buyers needing a coupling that connects two male threads or two female threads of the same size should select a different fitting type.

Fits Class 150 threaded assemblies.

The bushing threads directly into standard NPT fittings, valves or equipment ports without special tools beyond a wrench on the hex flats. Its compact hex profile allows installation in tighter pipe runs where a larger coupling would interfere. Using one reducing bushing replaces the need to stock multiple step-down nipples and couplings.

Questions about this item

What pipe thread size must my existing fitting have to accept the 1/2 in male NPT end?

The male end uses 1/2 in NPT with 14 threads per inch, so the mating female fitting must match that size and pitch.

Will the Class 150 pressure rating of this malleable iron bushing match the rating of my older Class 150 fittings?

Yes, both carry a Class 150 rating, so the bushing will not reduce the pressure capacity of a system built to that class.

How can I confirm the threads are cut correctly after I install the bushing?

Check that the male end engages 11 1/2 threads per inch on the 1-1/2 in side and 14 threads per inch on the 1/2 in side without binding or cross-threading.
