Description
304 Stainless Steel 150# Threaded Hex Bushing - SP112
Charman Inc 304 Stainless Steel 150# Threaded Hex Bushings - SP112 provide a compact way to reduce between two different NPT pipe sizes in a threaded piping system. Manufactured from 304 stainless steel, these reducing bushings combine a larger male NPT connection with a smaller female NPT connection and are available in a broad selection of reducing sizes.
The hex-body configuration provides wrench flats for installation while allowing the bushing to thread directly into a compatible larger female NPT connection. The smaller female NPT opening then accepts the reduced-size male-threaded pipe, nipple, fitting, valve, instrument, or equipment connection.

What Is an SP112 Hex Bushing?
The Charman Inc SP112 hex bushing is a threaded reducing fitting with a larger male NPT connection on the outside and a smaller female NPT connection through the center. The male connection threads into a compatible female NPT component while the female connection accepts a smaller male NPT component.
This configuration provides a compact method of reducing threaded connection size without using a separate reducing coupling or multiple fittings. The hex-shaped exterior provides wrench flats that help with installation and removal.
Understanding Hex Bushing Sizes
Hex bushings are identified by the larger male NPT size first and the smaller female NPT size second. For example, a 1" x 1/2" hex bushing has a 1" male NPT connection and a 1/2" female NPT connection.
When selecting a bushing, confirm both the larger female connection that will receive the bushing and the smaller male-threaded component that will connect to the bushing.
Why Choose a 304 Stainless Steel Hex Bushing?
304 Stainless Steel Construction
- Provides good general corrosion resistance
- Suitable for many industrial and commercial environments
- Durable construction for threaded piping systems
- Useful where stainless steel piping components are specified
- Well suited for process, mechanical, utility, and equipment applications
Compact Size Reduction
- Reduces between two nominal pipe sizes
- Male NPT x female NPT configuration
- Threads directly into a compatible female connection
- Hex exterior provides wrench flats
- Can simplify threaded reducing assemblies
Common Applications
Industrial & Process Piping
- Process piping systems
- Industrial utility piping
- Equipment connections
- Stainless steel threaded assemblies
- Maintenance and repair installations
Instrumentation & Mechanical Systems
- Instrumentation connections
- Valve and gauge installations
- Manifold assemblies
- Mechanical piping systems
- Threaded equipment ports
Hex Bushing vs. Reducing Coupling
A hex bushing uses a male NPT connection on the larger side and a female NPT connection on the reduced side. It threads directly into a larger female-threaded connection and reduces that opening to a smaller female NPT size.
A reducing coupling generally has female threaded connections on both ends. The correct fitting depends on the thread configuration of the components being connected and the available installation space.
Where an SP112 Hex Bushing Makes Sense
- Reducing a female NPT port to a smaller pipe size
- Connecting smaller piping to larger threaded fittings
- Reducing valve or equipment connection sizes
- Instrumentation and gauge connections
- Compact manifold assemblies
- Industrial process and utility piping
- Maintenance, repair, and retrofit installations
Ask Willy: Need Stainless Steel Fitting Information?
Review the Charman Inc stainless steel fittings specification sheet for product and dimensional information on SP112 threaded fittings, or use the complete stainless steel fittings catalog to compare available fitting styles, configurations, and sizes before ordering.
Installation & Selection Guidance
- Confirm both nominal pipe sizes before ordering.
- The first size represents the larger male NPT connection.
- The second size represents the smaller female NPT connection.
- Verify that the male side will mate with the intended female NPT connection.
- Verify that the reduced female side will accept the intended male NPT component.
- Confirm that 304 stainless steel is compatible with the intended service.
- Inspect all threads for damage or contamination before assembly.
- Use a thread-sealing method appropriate for the system media, pressure, temperature, and application.
- Use the hex wrench flats for controlled installation.
- Avoid excessive tightening that could damage the bushing or mating component.
- Support connected piping to avoid excessive mechanical loading on the fitting.
- Confirm system pressure and temperature requirements before installation.
- Installation should be completed by qualified personnel and in accordance with applicable codes and specifications.
Product Selection Considerations
Larger Male Connection
The first size listed is the male NPT connection. Match this size to the larger female NPT fitting, valve, manifold, or equipment port that will receive the bushing.
Reduced Female Connection
The second size listed is the reduced female NPT connection. Match this size to the smaller male NPT pipe, nipple, fitting, instrument, or equipment connection.

Frequently Asked Questions
What is the Charman Inc SP112 hex bushing?
It is a 304 stainless steel 150# threaded reducing fitting with a larger male NPT connection and a smaller female NPT connection.
How do I read the bushing size?
The larger male NPT size is listed first and the smaller female NPT size is listed second. A 1" x 1/2" bushing therefore has a 1" male connection and a 1/2" female connection.
What material are these bushings made from?
The SP112 hex bushings in this listing are manufactured from 304 stainless steel.
Are these reducing fittings?
Yes. Each bushing reduces from the larger male NPT size to the smaller female NPT size shown for that variant.
Why does the fitting have a hex-shaped exterior?
The hex exterior provides wrench flats that can be used to install or remove the threaded bushing.
What is the difference between a hex bushing and a reducing coupling?
A hex bushing has a larger male NPT connection and a smaller female NPT connection. A reducing coupling generally uses female threaded connections on both sides.
Does a threaded hex bushing require welding?
No. The fitting uses male and female NPT threaded connections and does not require welding for normal threaded installation.
Can a hex bushing be used on a valve or equipment port?
A properly selected bushing can reduce a compatible female NPT valve, manifold, fitting, or equipment connection to a smaller female NPT size.
Should thread sealant be used?
Use a thread-sealing method appropriate for the system media, pressure, temperature, fitting materials, and applicable installation requirements.
How do I select the correct bushing?
Match the first size to the larger female NPT connection and the second size to the smaller male NPT component that will connect to the bushing.
