Construction Details
SCI Heavy Pattern Class 150 half 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 half coupling provides a female NPT threaded connection on one side for attaching compatible male-threaded pipe, nipples, instruments, valves, or other piping components.
Its compact configuration makes it useful where a full coupling is unnecessary, including compatible fabricated piping, vessel, tank, and equipment connections.

Frequently Asked Questions
What is a 150# stainless steel half coupling used for?
It provides a female-threaded connection for compatible pipe, instruments, valves, equipment, and fabricated piping connections.
What figure numbers identify this half coupling?
SCI identifies the heavy-pattern half coupling as FIG S3114HC for 304 stainless steel and FIG S3116HC for 316 stainless steel.
What stainless steel grades are available?
The half coupling is available in 304 stainless steel ASTM A351 CF8 and 316 stainless steel ASTM A351 CF8M configurations.
What type of connection does the half coupling use?
The half coupling provides a female NPT threaded connection for compatible male-threaded piping components.
What standard applies to the NPT threads?
The NPT threads conform to ASME B1.20.1.
How is a half coupling different from a full coupling?
A half coupling provides a threaded connection from one side, while a full coupling is designed to connect threaded components from both ends.
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 pipe size, stainless steel grade, NPT requirements, intended installation, process media, and operating conditions.
Important Ordering & Installation Notes
- Confirm the required pipe size.
- Select 304 or 316 stainless steel.
- Verify service compatibility.
- Use suitable thread sealant.
- Follow proper fabrication practices.
