Standard Specifications
Couplings generally conform to ASA B16.3 and pipe threads conform to ASA B2.1 standard for manufacturing. View the standard specifications chart.Stainless Steel Grades
SS couplings available from Shaw Stainless. View the various grades of stainless steel.Reference Catalog
View thousands of stainless steel pipe and tubing products and various services Shaw offers. This Reference Catalog identifies stainless steel pipe couplings and other pipe fittings through specification charts and illustrations.Additional Info
A coupling connects two pieces of pipe together. 150 lb cast couplings can come threaded or socket weld. If the two pipes being connected are not the same size, one would use a cast reducing coupling. Couplings are one of the most common pipe fittings and available in a variety of different alloys.Frequently Asked Questions
What sizes of 150 lb half couplings do you carry?
The product table on this page lists 304 and 316 stainless steel 150 lb half couplings: threaded (NPT) from 1/8" to 4". For other sizes or alloys, call (800) 282-9694 or send us a message.
How long is a threaded half coupling?
Column L2 in the chart is the overall length. A 1" half coupling measures 0.83" and a 2" one measures 1.10".
What do d1 and d3 mean in the half coupling chart?
Column d1 is the NPT thread size and column d3 the outside diameter. A 1" half coupling has a 1.56" outside diameter. See also our full couplings.
