Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping installations.
Male x Female Reduction
The larger outside connection uses male NPT threads while the smaller inside connection uses female NPT threads, allowing a smaller pipe or fitting to connect directly into a larger threaded opening.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides added protection against rust and corrosion in moisture-prone and outdoor environments.
Why Use a Hex Bushing?
Compact Size Reduction
A hex bushing provides pipe-size reduction within a very short fitting length, making it useful where installation space is limited.
Easy Wrench Installation
The hex-shaped head provides flat surfaces for wrench engagement, helping simplify tightening and removal during installation or maintenance.
Typical Applications
Commercial & Mechanical Piping
- Commercial plumbing systems
- HVAC piping
- Mechanical piping
- Water distribution
- Equipment connections
- Threaded size transitions
Galvanized Applications
- Outdoor piping
- Moist environments
- Water-service applications
- Industrial installations
- General galvanized piping systems

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 connection in a compact threaded fitting.
Which side of a hex bushing is male?
The outside, larger-diameter threads are male NPT. The smaller internal threads are female NPT.
Why does the bushing have a hex head?
The hex shape provides wrench flats that make the fitting easier to tighten or remove during installation and maintenance.
How is a hex bushing different from a reducing coupling?
A reducing coupling has female threads at both ends. A hex bushing has male threads on the outside and female threads on the inside, allowing it to screw directly into another female-threaded fitting.
Can a hex bushing save installation space?
Yes. Its compact male-to-female design can provide a shorter pipe-size transition than assemblies using multiple fittings.
What standard applies specifically to malleable iron bushings?
The supplied product information states that malleable bushings, plugs, and locknuts conform to ASME B16.14.
What standard applies to the galvanized coating?
Hot-dipped galvanized fittings conform to ASTM A153 according to the supplied product information.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Is this fitting UL Listed and FM Approved?
The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.
What sizes should I verify before ordering?
Confirm both the larger male NPT size and the smaller female NPT size to ensure the bushing matches the intended reduction.
Important Ordering & Installation Notes
- Confirm both the larger male NPT size and smaller female NPT size before ordering.
- The outside connection is male NPT and the internal connection is female NPT.
- Use the hex wrench flats for installation rather than gripping threaded surfaces whenever practical.
- Malleable bushings conform to ASME B16.14 according to the supplied product information.
- NPT threads conform to ASME B1.20.1.
- Hot-dipped galvanized fittings conform to ASTM A153.
- Use compatible galvanized pipe, fittings, thread sealant, and accepted threaded installation practices.
- Avoid damaging the galvanized coating during handling and installation.
- Verify system pressure, service, potable-water, code, and approval requirements before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
