AN 6230 is an O-ring size standard based on the US military (MIL) specification. It was originally created as an aircraft O-ring series, and it is mainly used for fixed sealing on cylindrical surfaces in a wide range of equipment.
All AN 6230 O-rings share the same cross-sectional thickness (3.53 mm wire diameter), with sizes ranging from AN 6230-1 to AN 6230-52 to cover large-diameter sealing needs.
Every AN 6230 size is exactly the same as the corresponding size in the AS568 standard, so the two can be used interchangeably.
