Frequently Asked Questions
What is a socket-weld reducing coupling used for?
A reducing coupling provides a straight inline transition between two different nominal pipe sizes in a socket-weld piping system.
What material are these fittings made from?
All variants in this listing are manufactured from 304 stainless steel.
What connection type does this reducing coupling use?
These fittings use socket-weld connections at both ends.
What pressure class are these fittings?
These stainless steel socket-weld reducing couplings are identified as 150 lb class fittings.
How are the sizes listed?
Sizes are shown as larger nominal connection x smaller nominal connection. For example, 2" x 1" identifies a reduction between 2" and 1" pipe sizes.
Is this the same as a full coupling?
No. A full coupling joins pipe of the same nominal size. This reducing coupling connects two different nominal pipe sizes.
Is this fitting threaded?
No. This listing is for socket-weld reducing couplings rather than NPT threaded reducing couplings.
Does this listing include 316 stainless steel?
No. The supplied SSPSW4R variants in this listing are 304 stainless steel.
How do I select the correct variant?
Confirm the larger nominal pipe size and smaller nominal pipe size required by the system, then select the matching reduction from the available options.
