The BS 1806 O-Ring size guide was issued by the British Standards Institution and lists all Imperial standard sizes. This standard includes all of the 5 main cross section groups in AS568 plus several sizes that are \u201cbetween\u201d AS568 Sizes. BS 1806 has been superseded by BS ISO 3601, however, since BS 1806 is still widely referenced in certain industries\/regions of the world, it is still relevant for cross reference purposes.<\/p>\n
