Socket weld items: dimensions from our heavy pattern (MSS SP-114) data sheet
Each socket weld item's product page links our heavy pattern (MSS SP-114) data sheet, so that sheet's chart is shown here. Socket weld items are sold from 1/4"; the sheet also lists 1/8". This chart uses its own drawing's letters, so a letter can stand for a different dimension than in the threaded chart. SB and SD are on the socket weld end drawing; the other letters are on the thread end drawing.

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

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 full couplings do you carry?
The product table on this page lists 304 and 316 stainless steel 150 lb full couplings: threaded (NPT) from 1/8" to 4" and socket weld from 1/4" to 4". For other sizes or alloys, call (800) 282-9694 or send us a message.
How long is a threaded full coupling?
Column L2 in the threaded chart is the overall length. A 1" threaded full coupling measures 1.69" and a 2" one measures 2.20".
What is the difference between a full coupling and a reducing coupling?
A full coupling connects two pipes of the same size. If the two pipes are not the same size, a reducing coupling is used. See our reducing couplings and half couplings.
Why does this page have two charts?
Threaded and socket weld full couplings have different data sheets. Each threaded item's product page links our 150 lb threaded (NPT) data sheet, shown in the first chart; each socket weld item's product page links our heavy pattern (MSS SP-114) data sheet, shown in the second chart. Each chart uses the letters of its own drawing.
How do I get a price?
Prices are listed in the product table on this page. For a size, end connection or alloy that is not listed, call (800) 282-9694 or send us a message.
