There are two main o-ring sizing types: standard and metric. O-rings Part 1: Inside diameters, cross-sections, tolerances and size identification code.

Common Metric O-Rings Sizes Tolerances var y by use, please see our tolerance pages. Thousands of non-standard sizes are available in stock or can be made within a few weeks typically without tooling fees so no need to settle for a less than optimal fit.

O-rings manufactured out of compounds with different shrinkage rates (other than AN) will produce slightly different dimensions and tolerances.

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.
