MAIN has been a leader in manufacturing and distribution of standard and custom hydraulic
flanges and components for the last 60 years.
Our mission is to:
1. Provide quality hydraulic flanges at the time they are needed for an
2. Provide flanges that conform to international standards as well as U.S.
3. Provide custom flanges quickly—generally within 4 to 5 days.
4. Be at the forefront of standards work at both the national (SAE and
NFPA) and international (ISO) level.
What this means to our customers is that they are dealing with a company that is QUICK, INFORMED, and DEPENDABLE, getting them the
correct high quality part on time.
QUICK comes from MAIN’s $5 million finished goods inventory, which includes over 6000 different items. MAIN manufactures
flanges to SAE, ISO, DIN, JIS, and other international mounting patterns. MAIN has
flanges to many different company mounting patterns as well. Metric flanges; metric,
SAE, British, and ISO threads; imperial and metric pipe and tube, are all stocked, in
reducing sizes as well.
Another aspect of quickness is MAIN’s inventory of 150 tons of MRR special quality
carbon steel and 50 tons of stainless-steel raw material and MAIN’s manufacturing agility (state of the art machines and tooling allowing setup changes for some machines in
as little as 10 minutes). This means that the special crosses, double elbows, flange pad
adapters, gauge port adapters, and drilled manifold are done quickly. Turnaround on spe-

cials is generally days, not weeks. The MRR special quality steel means that the steel
is verified to a higher quality than most machine shops can get from the steel service
centers. Parts can be shipped with full material certification from U.S. sources. MAIN
is a U.S. manufacturer of flanges although some of our stock material may be of foreign
melt but U.S. rolling.
INFORMED comes from MAIN’s staff of dedicated and experienced professionals.
MAIN’s engineers are active on SAE and NFPA committees and have served as the US Expert to ISO technical committees. MAIN’s engineers have over 100 years total experience
in hydraulic flanges and components.
DEPENDABLE comes from MAIN’s 60
years of service to customers and its extensive quality control procedures assuring that
the customer gets the right part right away.
MAIN’s website, MAINmfg.com, provides a
lot of good information on how to specify and
measure hydraulic flanges and mountings. It
also helps in specifying metric flanges. From
the website you can download multiple catalogs and flyers and see a video about MAIN
and hydraulic flanges.
