Description
316 Stainless Steel 150# Threaded Half Coupling - SP112
Charman Inc 316 Stainless Steel 150# Threaded Half Couplings - SP112 provide a compact female-threaded connection point for stainless steel piping and fabrication applications. Manufactured from 316 stainless steel, these half couplings are available in nominal pipe sizes from 1/4" through 3".
Unlike a full coupling with threaded connections at both ends, a half coupling provides a single female threaded connection. This configuration is commonly selected when a threaded branch, equipment connection, vessel connection, or other compact threaded outlet is required.

What Is an SP112 Threaded Half Coupling?
The Charman Inc SP112 threaded half coupling is a compact 316 stainless steel fitting that provides a female threaded connection for a compatible male-threaded piping component.
A half coupling differs from a standard full coupling because it does not provide two opposing female-threaded ends for joining two pieces of pipe. Instead, its compact single-connection configuration makes it useful where a threaded connection point or outlet is needed.
Why Choose a 316 Stainless Steel SP112 Half Coupling?
316 Stainless Steel Construction
- Provides strong general corrosion resistance
- Useful in many industrial and process environments
- Suitable where 316 stainless steel piping components are specified
- Durable construction for threaded piping applications
- Well suited for utility, mechanical, process, and equipment applications
Compact Threaded Connection
- Provides a single female threaded connection point
- Accepts compatible male-threaded components
- Compact alternative to a full coupling where two threaded ends are not required
- Useful for branch and equipment connection applications
- Available across a broad range of nominal pipe sizes
Common Applications
Industrial & Process Applications
- Process piping systems
- Industrial utility systems
- Threaded branch connections
- Equipment connections
- Stainless steel fabrication assemblies
Commercial & Mechanical Applications
- Mechanical piping systems
- Instrumentation connection points
- Threaded accessory connections
- Maintenance and repair installations
- Equipment and piping assemblies
Half Coupling vs. Full Coupling
A full threaded coupling has female threaded connections at both ends and is typically used to join two compatible male-threaded piping components. A half coupling provides a single female threaded connection in a shorter, more compact configuration.
Select a half coupling when the installation requires one threaded connection point rather than an inline connection between two threaded components.
Where an SP112 Half Coupling Makes Sense
- Creating a compact female-threaded connection point
- Threaded branch and outlet applications
- Equipment connection points
- Instrumentation connections
- Stainless steel fabrication assemblies
- Industrial process and utility systems
- Mechanical piping applications
- Maintenance, repair, and retrofit work
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 the required nominal pipe size before ordering.
- Verify that the mating threaded component is compatible with the female connection.
- Confirm that a half coupling is appropriate for the intended installation.
- Confirm that 316 stainless steel is compatible with the intended service.
- Inspect the fitting and mating threads for damage or contamination before assembly.
- Use a thread-sealing method appropriate for the system media, pressure, temperature, and application.
- Begin threaded assembly carefully to reduce the risk of cross-threading.
- Tighten threaded connections using appropriate tools and accepted piping practices.
- Avoid excessive tightening that could damage the fitting or mating threads.
- Confirm system pressure and temperature requirements before installation.
- Pressure-test completed assemblies where required.
- Installation and any associated fabrication should be completed by qualified personnel in accordance with applicable codes and specifications.
Product Selection Considerations
Nominal Pipe Size
Select the SP112 half coupling that matches the nominal size of the compatible male-threaded component. Available sizes range from 1/4" through 3".
Half vs. Full Coupling
Use a half coupling when only one female threaded connection point is required. Select a full coupling when two compatible male-threaded components need to be joined inline.

What pressure class are these fittings?
The SP112 half couplings in this listing are 150# fittings.
What sizes are available?
This listing includes 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", and 3" nominal pipe sizes.
What is the difference between a half coupling and a full coupling?
A full coupling has female threaded connections at both ends for joining two compatible male-threaded components. A half coupling provides one female threaded connection in a more compact configuration.
Can a half coupling be used as an inline coupling?
A full coupling is generally the appropriate configuration when two male-threaded piping components must be joined inline. A half coupling is intended to provide a single threaded connection point.
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 choose the correct half coupling size?
Select the nominal pipe size that matches the compatible male-threaded component being connected.
