Description
Stainless Steel 150# NPT Hex Bushing
Stainless Steel 150# NPT Hex Bushings provide a compact threaded transition between different nominal pipe sizes. Available in both 304 and 316 stainless steel, these reducing bushings feature a male NPT connection on the larger end and a female NPT connection on the smaller end.
The SSP4HB series is manufactured from 304 stainless steel, while the SSP6HB series is manufactured from 316 stainless steel. Multiple reducing combinations are available from 1/4" x 1/8" through 4" x 3", depending on the selected stainless steel grade.

Choose 304 or 316 Stainless Steel
304 Stainless Steel
The SSP4HB series is manufactured from 304 stainless steel and provides corrosion resistance and durability for industrial, commercial, mechanical, and general threaded piping applications where 304 stainless steel is compatible with the service conditions.
316 Stainless Steel
The SSP6HB series provides the same reducing hex-bushing configuration in 316 stainless steel. Select 316 stainless steel when that material grade is specified or required for the piping system or application.
Reducing Hex Bushing Configuration
Male x Female NPT
- Larger male NPT connection
- Smaller female NPT connection
- Reduces between different nominal pipe sizes
- Connects directly into compatible female NPT ports
- Accepts a compatible smaller male NPT connection
Hex Body
- Hex-shaped exterior provides wrench flats
- Designed for threaded installation
- Compact alternative to multi-fitting reductions
- Useful where installation space is limited
- Available in numerous reducing combinations
Understanding Hex Bushing Sizes
Hex-bushing sizes are shown as larger connection x smaller connection. For example, a 1" x 1/2" hex bushing is used to transition from a 1" female NPT connection to a 1/2" female connection through the bushing.
Because not every reducing combination is offered in both stainless steel grades, select the exact size and material combination shown in the product options before ordering.
Performance Features
150 lb Class
These hex bushings are identified as 150 lb class stainless steel threaded fittings.
NPT Threaded
Male and female NPT connections provide a threaded transition between compatible piping components of different nominal sizes.
Broad Reduction Range
Multiple reducing combinations are available to transition between commonly used threaded pipe sizes.
Common Applications
Industrial & Process Piping
- Industrial piping systems
- Process piping
- Utility piping
- Equipment connections
- Valve and instrument connections
- Maintenance and repair installations
Commercial & Mechanical Piping
- Commercial mechanical systems
- Stainless steel piping assemblies
- Equipment rooms
- Threaded size reductions
- Compact equipment connections
- General stainless steel threaded piping
Selecting the Correct Hex Bushing
Confirm the larger connection size, smaller connection size, and stainless steel grade before ordering. SSP4HB-series bushings are 304 stainless steel, while SSP6HB-series bushings are 316 stainless steel.
Size availability is not identical between the two stainless steel grades. Select only from the exact combinations shown in the product options.

Installation & Selection Guidance
- Confirm both nominal connection sizes before ordering.
- Select either 304 or 316 stainless steel according to the piping specification.
- Verify that a male NPT x female NPT reducing bushing is required.
- Confirm stainless steel compatibility with the intended service.
- Use thread sealant suitable for the piping material and conveyed media.
- Avoid cross-threading during installation.
- Use the hex wrench flats for controlled installation.
- Use appropriate practices to minimize stainless steel thread galling.
- Do not over-tighten threaded stainless steel fittings.
- Confirm pressure and temperature requirements for the complete piping system.
- Inspect completed connections for leakage before placing the system into service.
- Follow applicable piping codes and project specifications.

Frequently Asked Questions
What is a hex bushing used for?
A hex bushing is used to reduce from a larger threaded connection to a smaller threaded connection in a piping system.
Are these available in both 304 and 316 stainless steel?
Yes. This listing includes SSP4HB 304 stainless steel and SSP6HB 316 stainless steel variants.
What is the difference between SSP4HB and SSP6HB?
SSP4HB-series bushings are manufactured from 304 stainless steel, while SSP6HB-series bushings are manufactured from 316 stainless steel.
What connection type does a hex bushing use?
These reducing bushings use a larger male NPT connection and a smaller female NPT connection.
How are the bushing sizes listed?
Sizes are shown as the larger nominal connection followed by the smaller nominal connection. For example, 2" x 1" identifies a reduction from 2" to 1".
What pressure class are these bushings?
These stainless steel threaded hex bushings are identified as 150 lb class fittings.
Are all size combinations available in both grades?
No. The available 304 and 316 stainless steel size combinations vary. Select only from the exact variants shown in this listing.
Why does the fitting have a hex-shaped body?
The hex exterior provides wrench flats to assist with controlled threaded installation.
How do I select the correct variant?
Confirm the larger connection size, smaller connection size, and required 304 or 316 stainless steel grade before ordering.
