Description
150# Black Malleable Iron Hex Bushing
150# Black Malleable Iron Hex Bushings are designed to reduce between different pipe sizes in threaded piping systems. The fitting features male NPT threads on the outside and female NPT threads on the inside, allowing a smaller threaded connection to be adapted into a larger female opening.
Manufactured from durable malleable iron, these Class 150 bushings are suitable for industrial, commercial, plumbing, HVAC, gas, oil, and general mechanical piping applications. The external hex head provides wrench flats for easier tightening and installation.

Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping systems.
Reducing Configuration
The bushing threads into a larger female connection and provides a smaller female threaded opening, allowing an efficient transition between nominal pipe sizes.
Hex Head Design
The external hex profile provides wrench flats that make it easier to tighten or remove the bushing during installation and maintenance.
Typical Applications
Industrial & Mechanical Piping
- Industrial piping systems
- Commercial piping
- Mechanical systems
- HVAC piping
- General threaded pipe installations
Common Services
- Plumbing systems
- Gas piping
- Oil piping
- General utility piping
- Threaded equipment connections
Reduce Pipe Size with One Fitting
A hex bushing provides a compact method of reducing a larger female-threaded opening to a smaller female-threaded connection. This can reduce the number of fittings required compared with using multiple adapters or reducing components.

Frequently Asked Questions
What is a hex bushing used for?
A hex bushing is used to reduce a larger female-threaded connection to a smaller female-threaded connection in a piping system.
What type of threads does the bushing have?
The outside of the bushing has male NPT threads, while the inside has female NPT threads.
Why does the bushing have a hex head?
The hex-shaped exterior provides wrench flats, making the fitting easier to tighten or remove during installation and maintenance.
Does a hex bushing connect two different pipe sizes?
Yes. The fitting is specifically designed to transition from a larger threaded connection to a smaller threaded connection.
What material is this fitting made from?
The bushing is manufactured from malleable iron castings conforming to ASTM A197.
What standard applies specifically to malleable bushings?
The supplied product information states that malleable bushings, plugs, and locknuts conform to ASME B16.14.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Is this a Class 150 fitting?
Yes. This is a 150# black malleable iron hex bushing.
Is this fitting UL Listed and FM Approved?
Yes. The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.

Important Ordering & Installation Notes
- Confirm both the larger male thread size and smaller female thread size before ordering.
- This is a reducing fitting with male NPT threads outside and female NPT threads inside.
- NPT threads conform to ASME B1.20.1.
- Malleable bushings conform to ASME B16.14 according to the supplied product information.
- Use the hex flats for wrench installation rather than applying installation force to threaded pipe connected to the bushing.
- Use compatible thread sealant and accepted threaded piping installation practices.
- Verify system pressure, service, code, and approval requirements before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
