Product Info
Our 304 and 316 stainless 3000 lb forged half couplings are available in a variety of sizes to fit any piping configuration. We also carry an inventory of full and reducing couplings. Our inventory includes: threaded half couplings, threaded reducing couplings, socket weld half couplings and socket weld reducing couplings. We can accommodate any need with our wide-ranging and hard to find sizes. Great stainless steel strength and corrosion resistance for many applications in harsh environments. View our stainless steel product line card.Dimensions
Dimensions in inches, from our forged fitting data sheets. The columns use the letters on our drawings; not every drawing marks every letter. The threaded and socket weld drawings use some of the same letters for different dimensions.
Our data sheets print Class 3000 and Class 6000 columns for some dimensions; the charts here show the Class 3000 columns.

This chart combines our two socket weld data sheets: B, D, C, J from the elbow, tee and cross sheet; F and its tolerance from the coupling and cap sheet.

Where a cell shows two figures, both are printed on our data sheet, which does not label them separately.
Standard Specifications
3000# couplings are manufactured in accordance with ASTM A182 for material and ANSI B16.11 for dimensional specifications.Stainless Steel Grades
SS Forged Couplings available from Shaw Stainless. View the various grades of stainless steel.Reference Catalog
View thousands of stainless steel pipe and tubing products. Our Reference Catalog identifies stainless steel pipe couplings and other pipe fittings through specification charts and illustrations. Some dimensions in the Reference Catalog differ from the charts on this page.Additional Info
Forged couplings connect two pipes together. 3000# couplings can come threaded or socket weld. If two pipes being connected are not of the same size, a forged reducing coupling can be used. Couplings are a common fitting in a pipe system.Frequently Asked Questions
What sizes of 3000 lb forged half couplings do you carry?
The product table on this page lists 304 and 316 stainless steel 3000 lb forged half couplings, threaded and socket weld, from 1/4" to 2". For other sizes or grades, call (800) 282-9694 or send us a message.
How long is a half coupling?
For threaded half couplings our data sheet gives no separate length: its drawing marks half of the full coupling's end-to-end length W (W/2), and the chart lists W. For socket weld half couplings the chart gives the laying length beyond the socket (F).
Why does this page have two charts?
Our data sheets have threaded and socket weld charts, each with its own drawing. The socket weld chart on this page combines our two socket weld sheets, because the drawings on each sheet use letters from the other. Each chart uses the letters on its own drawing.
What does Class 3000 mean on the charts?
Class 3000 is the pressure class of these fittings (3000# in the product table). Our data sheets give some dimensions for Class 3000 and Class 6000; the charts show the Class 3000 columns.
How do I get a price?
Prices are listed in the product table on this page. For a size, end connection or grade that is not listed, call (800) 282-9694 or send us a message.
