Metric o-rings sizes can be very confusing and it can be difficult to find the correct size because there are many size standards such a the British Standard (BS), Japanese Industrial Stand (JIS) and the German Standard (DIN). Then there are metric o-rings which are simply made to stated metric sizes. The standard nomenclature for designating a metric o-ring is Inside Diameter (ID) x Cross Section (CS). This listing is for o-rings of the stated dimensions. The standard to which they are made will be stated if applicable.
