Global O-Ring and Seal carries a full line of o-rings in all standard AS568 and most metric sizes. We are also here to guide you through the sizing process. Give us a call at 832-448-5550 to speak with an Industry Expert, or if you are local to the Houston area, come visit us at our Will Call department for more help on sizing o-rings.

In the US the most common standard inch sizes are per SAE AS568C specification (e.g. AS568-214). ISO 3601-1: contains the most commonly used standard sizes, both inch and metric, worldwide. The UK also has standards sizes known as BS sizes, typically ranging from BS001 to BS932. Several other size specifications also exist.

An O-ring is a solid-rubber seal shaped like a doughnut or torus. When compressed between mating surfaces, an O-ring blocks the passage of 20 sizes for boss seals. The standard sizes are also used for most military specifications. Cross-sectional diameters range from 0.040 to 0.275 inch. Inside diameters range from 0.029 to

The wide ranges of ID dimensions of O-Rings are developed around standard inch fractional sizes. This sizing system is referred to as the

The proper o-ring size is a fundamental aspect of proper o-ring performance. Whether your application conforms to U.S., Japanese JIS, British BS, or Common Metric sizing for o-rings,

The Japanese Industrial Standard (JIS B 2401) contains three groups; aerospace group, general purpose group, and traditional group. These o-ring sizes are unique to Japan's automotive, semiconductor, and manufacturing industries. JIS O-Ring Groups. Aerospace Group. 367 sizes and follows ISO 3601-1 very closely (with a few extra sizes).
