SKF supplies all O-rings with dimensional tolerances in accordance with ISO 3601-1: Class B (table 2). They are suitable for any elastomer material provided 

The metric sizes are based on the International Standard ISO 3601-1:2002. Metric O-ring measurements are grouped into two series: G and A. Each has a different application. The G series is used for general purpose applications, while the A series is for Aerospace applications. O-ring seal measurements are based on their diameters.
