MAIN Manufacturing is a leading flange manufacturer in the United States.
MAIN manufactures components to SAE, ISO, Japanese, German, British and many company standards with nearly 7,000 special blueprints going back 60 years. Most non-stock items are available in a few days. MAIN stocks 200+ tons of raw steel and STAINLESS to 15” X 15”. Our staff can be of great assistance with up to 40 years experience and working on SAE, NFPA, and ISO standards committees.
MAIN Manufacturing Products, Inc. has manufactured hundreds of “special flanges” which do not fit any established bolt hole spacing. We welcome the opportunity to quote on any particular flange not shown in either the catalog or on-line. With 60 years of manufacturing, the flange you need could easily be on our shelves but not cataloged. This includes flanges to ISO 6162, ISO 6164, JIS, or DIN standards and/or flanges with blind, ISO 6149, BSPP, BSPT, or butt weld ports. Run tees, branch tees, wyes, and crosses are also available. For more options call 800-521-7918.
