Description
316 Stainless Steel 150# Threaded Reducing Coupling - SP114
Charman 316 Stainless Steel SP114 Threaded Reducing Couplings provide a straight threaded transition between two different nominal pipe sizes. Manufactured from 316 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 shown here includes twenty configurations ranging from 1/4" x 1/8" through 3" x 2". Each variant uses two different nominal connection sizes, allowing the fitting to transition directly from a larger threaded connection to a smaller threaded connection in plumbing, industrial, process, maintenance, and general piping applications.

What Is an SP114 Threaded Reducing Coupling?
A 316 stainless steel SP114 threaded reducing coupling is a straight fitting designed to connect two compatible threaded piping components with different nominal sizes. The fitting transitions from a larger connection to a smaller connection within one compact coupling body.
This configuration allows a threaded piping system to change nominal size without using a separate reducer and standard coupling. Each Charman SKU represents one specific larger-to-smaller connection combination.
Why Choose a 316 Stainless Steel SP114 Threaded Reducing Coupling?

Available SP114 Reducing Coupling Configurations
The 316 Stainless Steel 150# Threaded Reducing Coupling - SP114 is available in twenty 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 exact 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 unequal connection 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 316 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 316 stainless steel.
Are these threaded fittings?
Yes. These SP114 Reducing Couplings are designed for compatible threaded piping connections.
How many configurations are included?
This listing contains twenty 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 316540, 316542, 316544, 316545, 316547, 316549, 316550, 316552, 316553, 316555, 316556, 316558, 316559, 316560, 316562, 316563, 316564, 316565, 316571, and 316575.
