Description
316 Stainless Steel 150# Threaded Coupling - SP114
Charman 316 Stainless Steel SP114 Threaded Couplings provide a straight connection between compatible threaded piping components of the same nominal size. Manufactured from 316 stainless steel, these couplings are available in sizes from 1/8" through 3" for plumbing, industrial, process, maintenance, and general piping applications where corrosion resistance and a dependable threaded connection are required.
The SP114 Coupling uses two threaded openings of the same nominal size to join compatible piping components in a straight run. Select the coupling according to the required nominal pipe size and confirm thread compatibility, material requirements, and system conditions before installation.
Product Highlights
- SP114 coupling design
- Two threaded openings
- 316 stainless steel construction
- Ten nominal sizes available
- Designed for straight pipe connections
- Available in sizes ranging from 1/8" through 3"
- Uses matching nominal connection sizes at both coupling ends
- Useful for plumbing, industrial, process, and general threaded piping systems
What Is an SP114 Threaded Coupling?
A 316 stainless steel SP114 threaded coupling is a straight fitting designed to connect two compatible threaded piping components of the same nominal size. The coupling provides a compact joining point within a threaded piping system.
Charman offers this SP114 Coupling family in ten nominal sizes. Because both ends of each standard coupling use the same listed nominal size, the fitting is selected according to the size of the two components being joined.

Available SP114 Coupling Sizes
The 316 Stainless Steel 150# Threaded Coupling - SP114 is available in 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", and 3" nominal sizes. Each size has its own Charman part number for accurate ordering.
The ten-size range allows the same SP114 Coupling family to be used across several common threaded piping sizes. Match the coupling to the nominal size of both piping components before ordering.
Standard Coupling vs. Reducing Coupling
SP114 Standard Coupling
- Two threaded openings
- Matching nominal connection sizes
- Creates a straight pipe connection
- Joins two same-size piping components
- Selected where no pipe-size change is required
Reducing Coupling
- Two threaded openings
- Uses unequal connection sizes
- Creates a straight size transition
- Available as a separate fitting family
- Selected where the piping diameter must change
Where a Charman SP114 Coupling Makes Sense
- For straight threaded connections
- During piping repair or modification
- For joining matching nominal pipe sizes
- Where 316 stainless steel construction is appropriate
- For compatible plumbing, industrial, and process piping systems
- When two same-size threaded piping components need a compact straight connection
Installation & Selection Considerations
- Select the coupling size that matches the piping.
- Confirm both mating threads are compatible before installation.
- 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
Nominal Size
Select the 316 Stainless Steel 150# Threaded Coupling - SP114 according to the nominal size of the two components being joined. This listing includes sizes from 1/8" through 3".
Material Requirements
Confirm whether 316 stainless steel is appropriate for the intended service media, environment, pressure, temperature, and overall piping system before ordering.
Review the Charman Inc stainless steel fittings specification sheet for product and dimensional information on the SP114 threaded 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 Coupling?
Charman identifies this product family as a 316 stainless steel fitting.
What sizes are available?
This listing includes 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", and 3" nominal sizes.
Are these couplings threaded?
Yes. These SP114 Couplings are designed for compatible threaded piping connections.
Which Charman SKUs are included?
The included part numbers are 316320, 316321, 316322, 316323, 316324, 316325, 316326, 316327, 316328, and 316330.
Are both coupling connections the same size?
Yes. Each standard coupling in this listing uses the same nominal connection size at both ends.
How is a standard coupling different from a reducing coupling?
A standard coupling joins two same-size threaded components, while a reducing coupling connects two different nominal pipe sizes.
Where can I review Charman stainless steel fitting information?
