Construction Details
SCI Heavy Pattern Class 150 reducer couplings are manufactured from cast stainless steel. The 304 stainless steel version uses ASTM A351 Grade CF8 material, while the 316 stainless steel version uses ASTM A351 Grade CF8M.
The reducing coupling incorporates two different female NPT connection sizes, allowing compatible male-threaded piping components of different nominal sizes to be joined directly.
The heavy-pattern bell-style body provides a compact threaded transition without requiring a separate full coupling and reducing bushing combination.
Design & Typical Applications
Reducer Coupling Design
- Heavy-pattern cast body
- Female NPT connections
- Two different connection sizes
- Bell-style reducing profile
- 304 or 316 stainless steel
Typical Applications
- Industrial process piping
- Water and utility systems
- Agricultural piping systems
- Petroleum transfer piping
- Chemical process systems
Installation & Selection Considerations
- Confirm both connection sizes.
- Select the proper stainless grade.
- Use compatible thread sealant.
- Inspect NPT threads before assembly.
- Avoid excessive tightening torque.
Use the SCI Heavy Pattern 150 Catalog to confirm reducer coupling figures, stainless steel materials, and threaded fitting information. The pipe chart can help confirm common pipe diameters and wall thicknesses for compatible piping.

Frequently Asked Questions
What is a 150# stainless steel reducer coupling used for?
It is used to join two compatible male-threaded piping components with different nominal pipe sizes.
What figure numbers identify this reducer coupling?
SCI identifies the heavy-pattern reducing coupling as FIG S3114RC for 304 stainless steel and FIG S3116RC for 316 stainless steel.
What stainless steel grades are available?
The reducer coupling is available in 304 stainless steel ASTM A351 CF8 and 316 stainless steel ASTM A351 CF8M configurations.
What type of connections does the coupling use?
The reducer coupling uses female NPT threaded connections of two different nominal sizes.
What standard applies to the NPT threads?
The NPT threads conform to ASME B1.20.1.
Why is this fitting also called a bell reducer?
Its body transitions between a larger and smaller threaded connection, creating the characteristic bell-shaped reducing profile.
Is 150# the same as a 150 PSI working pressure?
No. Class 150 identifies the fitting pressure class and should not be interpreted as a universal 150 PSI working-pressure rating.
What should I confirm before ordering?
Confirm both nominal connection sizes, stainless steel grade, NPT requirements, process media, and system operating conditions.
Important Ordering & Installation Notes
- Confirm both required connection sizes.
- Select 304 or 316 stainless steel.
- Verify service compatibility.
- Use suitable thread sealant.
- Avoid excessive thread torque.
