Dimensions
The charts below list concentric and eccentric reducer dimensions and approximate weights by schedule.
Dimensions in inches; approximate weight in pounds per fitting. ID = inside diameter, OD = outside diameter. A dash means no value is listed for that size and schedule. † We are confirming this weight; call us for it. The charts reproduce our full data sheet, including Schedule 160, XX Strong and sizes that are not in the product table (which lists Schedule 5S, 10S, 40S and 80S). Call us for availability.

Pipe Sizes & Weights
Select various butt weld reducer sizes, grades and schedules. Our
pipe sizes and weights chart will help you research individual product specifications.
Standard Specifications
Stainless steel butt weld reducers are manufactured to ASTM A403 with dimensional tolerances in accordance with MSS SP-43 for schedules 5s and 10s, and with ANSI B16.9 for schedules heavier than 10s. View the
standard specifications chart.

Additional Info
A butt weld pipe reducer enables there to be a change in pipe size to meet certain hydraulic flow requirements or sometimes it's just a matter of connecting two different pipe sizes. An eccentric butt welding reducer is a pipe fitting that is used when a pipe on the upstream side of the fitting is larger than the downstream side of the fitting. A concentric butt welding reducer works the same way, but resembles a cone and keeps fluid or gas more centered, whereas eccentric reducers have a parallel edge, which results in an offsetting center. Eccentric butt weld reducers are used if the same top or bottom level of the pipe is required.
Frequently Asked Questions
What sizes of eccentric reducers do you carry?
The product table on this page lists 304 and 316 stainless steel eccentric reducers from 3/4" × 1/2" to 12" × 10" in Schedule 5S, 10S, 40S and 80S. For other sizes, schedules or alloys, call (800) 282-9694 or send us a message.
When is an eccentric reducer used instead of a concentric reducer?
When the same top or bottom level of the pipe is required. An eccentric reducer has a parallel edge, which offsets its center; a concentric reducer resembles a cone and keeps the fluid or gas more centered. See our concentric reducers.
Do eccentric reducers have the same dimensions as concentric reducers?
Yes. Our data sheet gives one set of dimensions for both. The end-to-end length H depends on the large-end size: a 4" × 2" reducer measures 4" and a 6" × 4" measures 5-1/2".
How much does an eccentric reducer weigh?
It depends on the size and schedule. The charts on this page list approximate weights: a 6" × 4" eccentric reducer weighs about 4.31 lb in Schedule 10S and 8.99 lb in Schedule 40S.
Do you carry Schedule 160 and XX Strong eccentric reducers?
They are not in our online product table, which lists Schedule 5S, 10S, 40S and 80S; call (800) 282-9694 or send us a message to ask about availability. The second chart on this page lists their dimensions from our data sheet.
What standards do your butt weld reducers meet?
Our butt weld reducers generally conform to ASTM A403, with dimensional tolerances in accordance with MSS SP-43 for Schedule 5S and 10S and with ANSI B16.9 for schedules heavier than 10S.
How do I get a price?
Prices are listed in the product table on this page. If an item shows Quote (or $0.00 on a phone), or you need a size or schedule that is not listed, call (800) 282-9694 or send us a message.
