METRIC HYDRAULIC FLANGES
Main Manufacturing Products, Inc manufactures and stocks
many metric flanges, adapters, and couplings. These include ISO, DIN,
and JIS series to BSPP, BSPT, ISO 6149, and metric weldments.
Main Manufacturing has a special On-Line catalog that contains catalog sheets for three popular types of
metric flanges. These are SAE J518 Metric
Series, also called ISO 6162, JIS B2291 210K, and ISO 6164. This catalog can be
found here. Individual pages both in carbon and
stainless steel can also be found in the "Part# Index".
The SAE J518 Metric Series, is the most requested. Any SAE flange in
our standard catalog can be converted to the "Metric Series" by adding
an "M" and the bolt size at the end of the part number. Part number
1102-20-20 tapped for M10 bolts is 1102-20-20M10. The table below shows
the ISO preferred size but some pumps and valves use the secondary size
(shown with and asterisk '*').
