Description
304 Stainless Steel 150# Threaded Reducing Coupling - SP114
Charman 304 Stainless Steel SP114 Threaded Reducing Couplings provide a straight threaded transition between two different nominal pipe sizes. Manufactured from 304 stainless steel, these fittings are designed to connect compatible threaded piping components where a reduction in connection size is required.
The SP114 Reducing Coupling family includes twenty-six configurations ranging from 1/4" x 1/8" through 3" x 2". Each variant uses two different nominal connection sizes, allowing installers to select the exact transition required for plumbing, industrial, process, maintenance, and general threaded piping applications.

What Is an SP114 Threaded Reducing Coupling?
A 304 stainless steel SP114 threaded reducing coupling is a straight fitting designed to connect two compatible threaded piping components with different nominal connection sizes. The larger connection transitions directly to the smaller connection within the coupling body.
This configuration allows a piping system to change size without requiring a separate reducer and standard coupling. Each Charman SKU represents one specific larger-to-smaller connection combination.
Why Choose a 304 Stainless Steel SP114 Threaded Reducing Coupling?

Available SP114 Reducing Coupling Configurations
The 304 Stainless Steel 150# Threaded Reducing Coupling - SP114 is available in twenty-six connection combinations ranging from 1/4" x 1/8" through 3" x 2". Each configuration has its own Charman part number for accurate ordering.
Because every variant contains two different nominal sizes, both dimensions must be confirmed before ordering. Select the configuration that matches the larger and smaller threaded components required by the piping system.
How to Read a Reducing Coupling Size
Larger Connection
- Listed first
- Varies by SKU
- Represents the larger opening
- Must match the larger piping connection
- Should be confirmed before selecting the coupling
Smaller Connection
- Listed second
- Varies by SKU
- Represents the reduced opening
- Must match the smaller piping connection
- Both connection sizes should be checked before ordering
Standard Coupling vs. Reducing Coupling
SP114 Reducing Coupling
- Two threaded openings
- Uses two different nominal sizes
- Creates a straight piping transition
- Connects a larger size to a smaller size
- Selected where the piping diameter must change
SP114 Standard Coupling
- Two threaded openings
- Uses matching nominal sizes
- Creates a straight pipe connection
- Available as a separate Charman fitting
- Selected where both piping components are the same size
Where a Charman SP114 Reducing Coupling Makes Sense
- For threaded size transitions
- During piping repair or modification
- For joining two unequal nominal pipe sizes
- Where 304 stainless steel construction is appropriate
- For compatible plumbing, industrial, and process piping systems
- When a direct threaded transition is preferred over a multi-fitting reducing assembly
Installation & Selection Considerations
- Confirm both connection sizes before ordering.
- Match each coupling end to its mating threaded component.
- Inspect threaded surfaces for damage, debris, or contamination.
- Use a thread-sealing method appropriate for the intended piping system.
- Verify pressure, temperature, media, material, and installation requirements before use.
Product Selection Considerations
Connection Combination
Select the exact SP114 Reducing Coupling configuration required by the installation. The first dimension identifies the larger nominal connection and the second dimension identifies the smaller nominal connection.
System Requirements
Confirm both mating threads, piping material, service media, pressure, temperature, sealing requirements, and applicable installation conditions before selecting a reducing coupling.
Review the Charman Inc stainless steel fittings specification sheet for product and dimensional information on the SP114 threaded reducing coupling, or use the complete stainless steel fittings catalog to compare available fitting styles, configurations, and sizes before ordering.

Frequently Asked Questions
What material is the SP114 Reducing Coupling?
Charman identifies this fitting family as 304 stainless steel.
Are these threaded fittings?
Yes. These SP114 Reducing Couplings are designed for compatible threaded piping connections.
How many configurations are available?
This listing contains twenty-six SP114 Reducing Coupling size combinations.
Why are two sizes listed for each coupling?
The first dimension identifies the larger nominal connection and the second dimension identifies the smaller nominal connection.
How is a reducing coupling different from a standard coupling?
A reducing coupling connects two different nominal pipe sizes, while a standard coupling connects piping components of the same nominal size.
Which Charman SKUs are included?
The included part numbers are 304540 through 304560, 304562 through 304565, and 304575.
Where can I review Charman stainless steel fitting information?
The Charman Stainless Steel Fittings Spec Sheet and Complete Catalog are linked directly above for additional product and fitting information.
What should I confirm before ordering?
Confirm both nominal connection sizes, thread compatibility, material requirements, pressure, temperature, media, and installation conditions before ordering.
Important Ordering & Installation Notes
