JIS 210 Kgf/cm2 4-bolt square flange
JIS B 8363 4-bolt flange*
This connection is commonly used
in fluid power systems. There are
two pressure ratings. Type I (Code
61) is referred to as the “standard”
series and Type II (Code 62)is
the “6000 psi” series. The design
concept for both series is the
same, but the bolt hole spacing
and flanged head diameters are
larger for the higher pressure, Type
II connection. Both metric and
inch bolts are used. The female
(port) is an unthreaded hole with
four bolt holes in a rectangular

pattern around the port. The
male consists of a flanged head,
grooved for an O-Ring, and either
a captive flange or split flange
halves with bolt holes to match
the port. The seal takes place on
the O-Ring, which is compressed
between the flanged head and
the flat surface surrounding the
port. The threaded bolts hold the
connection together.
The JIS 4-bolt square flange
connection is similar in concept to
the SAE 4-bolt flange connection,
except that the JIS bolt pattern is
square and the flange itself
is different.
