Description
150# Cast Stainless Socket Weld Reducing Coupling 304
ASC / SCI 150# Cast 304 Stainless Socket Weld Reducing Couplings provide a compact transition between two different nominal pipe sizes in compatible stainless steel socket-weld piping systems.
Manufactured from cast 304 stainless steel, the S3714RC reducing coupling uses socket-weld connections on both ends for a permanent welded transition in industrial process piping, stainless steel piping, utility systems, and other compatible applications.

Construction Details
The SCI S3714RC family is designed as a 150# cast stainless steel reducing coupling manufactured from 304 stainless steel. The 304 stainless casting conforms to ASTM A351 ACI Grade CF8.
The fitting incorporates socket-weld connections at both ends, providing a permanent welded transition between compatible pipe sections of different nominal sizes.
Unlike a full coupling, the reducing configuration combines a straight in-line connection with a pipe-size transition in one compact fitting.
Reducing Design & Typical Applications
Reducing Coupling Design
- Straight in-line transition
- Two socket-weld connections
- Different connection sizes
- Cast 304 stainless body
- Permanent welded installation
Typical Applications
- Industrial process piping
- Stainless steel piping
- Utility piping systems
- Equipment connections
- General industrial service
Installation & Selection Considerations
- Confirm both required pipe sizes.
- Verify 304 stainless construction.
- Confirm socket-weld compatibility.
- Use proper welding procedures.
- Check system service requirements.

Use the supplied ASC / SCI documents to review the 150# socket-weld fitting family, stainless steel fitting information, and adjoining pipe diameter and wall-thickness references.

Frequently Asked Questions
What is the SCI item family for this reducing coupling?
This 150# cast 304 stainless steel socket-weld reducing coupling uses the S3714RC family designation.
What material is the reducing coupling?
The fitting is manufactured from cast 304 stainless steel.
What casting grade applies to the 304 version?
The 304 stainless steel casting conforms to ASTM A351 ACI Grade CF8.
What connections does the coupling use?
The fitting uses socket-weld connections on both ends for permanent welded installation.
What is a reducing coupling used for?
It connects two different nominal pipe sizes while maintaining a straight in-line piping configuration.
How is a reducing coupling different from a full coupling?
A reducing coupling transitions between different nominal pipe sizes, while a full coupling connects matching nominal pipe sizes.
Is 150# the same as a universal 150 PSI rating?
No. The 150# designation identifies the fitting family or class and should not be treated as a universal 150 PSI system pressure rating.
What should I confirm before ordering?
Confirm both pipe sizes, 304 stainless construction, the 150# fitting configuration, and socket-weld compatibility.
Important Ordering & Installation Notes
- Confirm both connection sizes.
- Verify 304 stainless construction.
- Check socket-weld compatibility.
- Follow proper welding procedures.
- Confirm system compatibility.
