Frequently Asked Questions
What is the SCI figure for this 304 socket-weld union?
This 150# cast 304 stainless steel socket-weld union is identified as Figure S3714U.
What material is the union?
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 union use?

What is a socket-weld union used for?
It provides an in-line connection that can be separated at the union for maintenance or equipment access without cutting the adjoining pipe.
How is a union different from a full coupling?
A union has a separable center connection, while a full coupling creates a continuous permanent connection between two pipe sections.
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 304 stainless construction, the required fitting class, pipe size, socket-weld connections, and compatibility with the intended system.
