Galvanized hex bushing reduces 1-1/2" male NPT to 1" female NPT for Class 150 piping

  • Galvanized coating resists corrosion in wet environments

  • Class 150 rating suits standard-pressure plumbing systems
  • Male 1-1/2" NPT to female 1" NPT adapts pipe sizes
  • Hex profile allows secure tightening with standard wrenches

1-1/2" MNPT x 1" FNPT Galvanized Hex Bushing

This galvanized hex bushing connects a 1-1/2 inch male NPT thread to a 1 inch female NPT thread. It is made from malleable iron with a galvanized coating for corrosion resistance. The fitting is rated for Class 150 pressure service.

Installers reducing pipe sizes in water or air lines

The bushing suits plumbers and maintenance technicians who need to step down from a larger male thread to a smaller female thread in a straight line. It is not intended for systems that require a union connection, a different thread standard, or a higher pressure class than Class 150.

Malleable iron body under continuous pressure

The galvanized malleable iron construction handles sustained operating pressures within the Class 150 rating without deformation. The hex profile allows secure installation with a wrench for a leak-free joint that remains tight over time.

Questions about this item

What male NPT size must the existing fitting have to accept this 1-1/2" MNPT hex bushing?

The bushing has a 1-1/2" male NPT thread with 11 threads per inch, so the mating fitting must provide a matching 1-1/2" female NPT opening.

Will the galvanized Class 150 malleable iron threads seal reliably against an older black iron pipe nipple?

Yes, both use the same 11 threads per inch NPT standard, so the 1" female NPT end will engage the older nipple without thread mismatch.

How can I confirm the bushing is seated correctly after installation?

The hex flats should be fully engaged with a wrench and the joint should hold pressure at the Class 150 rating without leaks at the 1" female NPT connection.
