Code 61, Code 62 Four Bolt Flange Connections are equivalent to and interchangeable with their German and Japanese counterparts. The main differences are: Metric Bolts, Metric O-Ring and JIS Type I series has a size 10. “Cat” flanges are the same diameter with the same bolt pattern, but thicker than a Code 62. Replacement of a “Cat” Flange with a Code 62 is made possible by using a Code 62 Split Flange Kit.
