What is the difference between the AS568A, AS568B and AS568C designation for o-rings?
An AS568 number is a three-digit suffix that identifies the o-ring's size. The SAE (Society of Automotive Engineers) published the original document that established these o-ring sizes. The AS in AS568 stands for Aerospace Standard. These o-ring sizes are standard throughout the o-ring industry and also in most military applications. AS568 is generally considered to be the U.S. size standard and there is no difference between the AS568A, AS568B or AS568C designations.
