How to Measure an O Ring (with only basic tools) Watch on. O-rings come in standard sizes, which are described by both the inner diameter (I.D.) and the cross section diameter (C.S.). The most common O-ring sizes are imperial (inch) sizes, and the two standard O-ring size charts are imperial and metric.

The standard sizes for o-rings include 20 sizes used to seal straight-thread tube fittings on a boss. A boss is a cylindrical projection on a casting or forging. The end of that projection is machined to provide a flat, smooth surface for sealing. Straight threads used with an o-ring provide a better seal than tapered threads used alone.

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 liquids or gases. Parco O-rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications.
