Hydraulic Flanges-Carbon & Stainless

Jan. 19, 2018

Many of those “special” flanges are shelf items for MAIN.  Many companies ship what they have in stock quickly.  MAIN has over 7000 different items on the shelf ready for same day shipment.  This includes reducing flanges, increaser flanges, Code 61 to Code 62 pad adapters, Socket weld American pipe and Japanese pipe, Socket weld inch and metric tube, Schedule 40, 80, 160, XXS butt weld, Threaded (SAE Straight Thread, ISO 6149, BSPP, BSPT, NPTF and others), inline, elbows, tee, cross, side outlets, gauge port adapters and many others.


Even if not in stock, we can turn it around quickly.  Main Manufacturing Products is the premier US manufacturer of hydraulic flanges and components for over 50 years.  MAIN’s engineers are active in the SAE, NFPA, and ISO standards committees for over 30 years and help write the standards.  With over 100 tons of raw steel specially ordered from mills to our own specifications (another 40 plus tons of stainless steel, copper nickel, aluminum, PVQ steels) the material is generally in house.  We regularly ship non-shelf specials in 4 days.
