Description
150# Stainless Steel Hex Bushing MSS SP114
150# Stainless Steel Hex Bushings MSS SP114 are threaded reducing fittings designed to transition from a larger female threaded connection to a smaller female threaded connection. The male x female configuration provides a compact way to reduce threaded connection size while the external hex body offers a convenient wrenching surface for installation and removal.
Available in 304 and 316 stainless steel, these fittings are manufactured as MSS SP-114 pattern fittings and are listed as low lead certified to NSF 61. Stainless steel construction helps resist corrosion, rust, scale, and contamination while providing dependable performance in commercial, industrial, water, and process piping systems.

Hex Bushing Construction
A hex bushing is designed to reduce the size of a compatible female threaded opening. The larger external male thread installs into the mating female connection, while the smaller internal female thread accepts a smaller male-threaded pipe or fitting.
The external hex body provides flat wrenching surfaces for installation and removal, helping simplify assembly in threaded piping systems.
Manufactured from 304 or 316 stainless steel, these bushings provide corrosion resistance and dependable performance in compatible commercial, industrial, water, and process piping applications.
Why Choose a Stainless Steel Hex Bushing?
Compact Threaded Reduction
- Reduces between different threaded connection sizes
- Male x female threaded configuration
- Provides the reduction within one fitting
- Compact alternative to multiple reducing components
- Useful for valves, equipment, fittings, and threaded piping assemblies
Hex Wrenching Surface
- External hex body provides flat wrench surfaces
- Simplifies tightening during installation
- Provides positive tool engagement
- Helps with removal during maintenance or system changes
- Compact profile for threaded piping installations
Hex Bushing vs. Reducing Coupling
Hex Bushing
- Male threaded connection on the larger end
- Female threaded connection on the smaller end
- Threads directly into a larger female opening
- Provides a compact threaded size reduction
- Hex body provides a wrenching surface
Reducing Coupling
- Female threaded connections on both ends
- Connects two male-threaded pipe sections
- Provides an in-line size reduction
- Does not thread directly into a female fitting like a bushing
- Different installation configuration from a hex bushing
304 vs. 316 Stainless Steel
304 Stainless Steel
304 stainless steel provides corrosion resistance for a wide range of general-purpose water, commercial, and industrial piping applications. It is commonly selected where dependable stainless steel performance is required without the additional corrosion resistance provided by 316 stainless steel.
316 Stainless Steel
316 stainless steel provides enhanced corrosion resistance for more aggressive environments and is commonly selected for applications involving chemicals, chlorides, process fluids, marine exposure, and other demanding service conditions.
Common Applications
Commercial & General Piping
- Water piping systems
- Commercial plumbing systems
- Mechanical piping installations
- Valve and equipment connections
- Threaded pipe size transitions
Industrial & Process Applications
- Industrial process piping
- Chemical processing systems
- Water treatment applications
- Process fluid piping
- Corrosion-resistant threaded assemblies
Installation & Selection Guidance
- Confirm both nominal connection sizes before ordering.
- Verify the required larger male thread size and smaller female thread size.
- Select 304 or 316 stainless steel based on the operating environment and required corrosion resistance.
- Verify that both mating threaded components are compatible with the bushing.
- Confirm system pressure and temperature requirements before installation.
- Verify compatibility between the stainless steel fitting and the system media.
- Use appropriate thread sealant suitable for the piping material, media, pressure, and temperature.
- Use the hex wrenching surfaces during installation rather than applying force to unsupported sections of the fitting.
- Avoid over-tightening threaded stainless steel connections.
- Inspect the completed connection for leaks before placing the system into service.
- Installation should be completed in accordance with applicable piping codes and project specifications.

Frequently Asked Questions
What is a stainless steel hex bushing used for?
A hex bushing is used to reduce a larger female threaded opening to a smaller female threaded connection.
What pressure class is this fitting?
This fitting is listed as a 150# stainless steel hex bushing.
What stainless steel grades are available?
These hex bushings are available in 304 and 316 stainless steel.
What pattern does this fitting conform to?
The fitting is identified as an MSS SP-114 pattern stainless steel fitting.
Is this hex bushing low lead certified?
Yes. The supplied product information identifies these fittings as low lead certified to NSF 61.
What connection configuration does a hex bushing use?
A hex bushing uses a larger male threaded connection and a smaller female threaded connection.
Why does the fitting have a hex body?
The external hex body provides flat wrenching surfaces for tightening and removing the fitting during installation or maintenance.
How is a hex bushing different from a reducing coupling?
A hex bushing uses male x female threaded connections and installs into a larger female opening. A reducing coupling uses female threaded connections on both ends to connect two male-threaded pipe sections.
What is the difference between 304 and 316 stainless steel?
Both grades provide strong corrosion resistance. 316 stainless steel generally provides additional resistance in more aggressive chemical, chloride, marine, and corrosive environments.
