Description
150# Stainless Steel Hex Bushing ISO 49
150# Stainless Steel Hex Bushings are standard-pattern cast fittings designed to reduce a larger female threaded connection to a smaller female threaded connection. The hex-body design provides a positive wrenching surface for installation and removal while maintaining a compact threaded transition.
The fitting family conforms to AISI 304 or 316 stainless steel material requirements and ISO 49-1983 (E) dimensional requirements. These fittings are also listed as low lead certified to NSF/ANSI 61.

Hex Bushing Design
A hex bushing is used to reduce a larger female threaded opening to a smaller female threaded connection within a single compact fitting.
The external hex profile provides wrench flats for installation and removal, making the fitting easier to tighten into a compatible female threaded port or fitting.
Threaded Reduction
The larger male threaded end installs into a compatible female threaded connection, while the smaller internal female thread accepts a smaller male-threaded pipe or fitting.
Confirm both nominal connection sizes before ordering and use an appropriate thread-sealing method for the application and piping media.
Stainless Steel Construction
The stainless steel construction provides corrosion resistance while helping prevent contamination associated with rust, scale, and small particles that can occur with some other metallic piping materials.
The supplied product information states that the material resists corrosive attack from hundreds of industrial and chemical solutions and mixtures and provides greater strength at elevated temperatures.
NSF/ANSI 61 Low Lead Certification
This fitting is listed as low lead certified to NSF/ANSI 61, supporting use in compatible potable-water applications where applicable code and system requirements are met.
Always confirm complete system requirements, local codes, operating conditions, and media compatibility before installation.
ISO 49 Standard Pattern
Dimensions conform to ISO 49-1983 (E), providing dimensional consistency for compatible standard-pattern cast stainless steel fittings.
Use the manufacturer dimensional document below to confirm hex bushing dimensions before ordering or installation.
Hex Bushing vs. Reducing Coupling
Hex Bushing
- Male thread x female thread configuration
- Installs into a larger female threaded opening
- Reduces to a smaller female connection
- Compact fitting with wrenching flats
Reducing Coupling
- Female connections on both ends
- Connects two male-threaded pipe sections
- Provides an in-line reduction
- Different installation configuration from a hex bushing
Common Applications
Commercial & General Piping
- Water piping systems
- Commercial plumbing
- General process piping
- Valve and equipment connections
- Threaded stainless steel piping assemblies
Industrial & Corrosive Service
- Industrial process piping
- Chemical handling systems
- Corrosion-resistant piping applications
- Elevated-temperature service where compatible
- Applications where rust and scale contamination are undesirable

Frequently Asked Questions
What is a 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 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 provides wrench flats for tightening and removing the fitting during installation or maintenance.
What stainless steel grades are used?
The supplied product information states that the fitting family conforms to AISI 304 or 316 stainless steel material requirements.
What dimensional standard applies?
The fitting dimensions conform to ISO 49-1983 (E).
Is this fitting low lead certified?
Yes. The supplied product information lists the fitting as low lead certified to NSF/ANSI 61.
How is a hex bushing different from a reducing coupling?
A hex bushing uses male x female connections and threads into a larger female opening. A reducing coupling uses female connections on both ends to join two different male-threaded pipe sizes.
