ISO/DIS 6162 4-Bolt Flange
For ISO/DIS 6162 4-Bolt Flange, governing standard is ISO/DIS 6162; region of origin is ISO Connections; thread type (tapered or parallel) is flange bolts; seat or flare angle is flat surface; seal method is The male is a flanged head with a groove for an O-ring to seat and either split or captive flange halves and bolt holes which match the port. The seal is made where the O-ring is compressed between the flanged head and the flat surface of the port. The connection is held by threaded bolts, recorded from its source on 2026-08-13.

What the source says
The seal is made where the O-ring is compressed between the flanged head and the flat surface of the port. The connection is held by threaded bolts. <https://brennaninc.com/fittings-101-flange> JIS 210 Kgf/cm2 4-Bolt Square Flange incorporates a JIS 4-bolt square flange connection which is comparable to SAE 4-bolt flange connections with one difference – the flange itself is different and the JIS bolt pattern is square. ISO Connections <https://brennaninc.com/fittings-101-flange> ISO/DIS 6162 4-Bolt Flange is another common connection found in fluid power systems. There are two pressure ratings for this connection- Code 61: PN 35/350 bar which is considered the standard series and Code 62: PN 415 bar which is the high pressure series. They maintain the same design, yet with the bold hole spacings and flanged head diameters being larger on the PN 415 bar high pressure connection. Inch or metric bolts are found in these connections, however there is an “M” stamped on the port if metric bolts are to be used. The female port of the fitting is a smooth, un-threaded port with four bolt holes set in a rectangular pattern in around the port. The male is a flanged head with a groove for an O-ring to seat and either split or captive flange halves and bolt holes which match the port. The seal is made where the O-ring is compressed between the flanged head and the flat surface of the port. The connection is held by threaded bolts.
