What are the sizes of o rings?
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 25.940 inches.
How do you determine the size of an o-ring?
The best way to size an o-ring is by measuring the CS (cross-section) and ID (inside diameter). For measuring the cross-section, it is best to use a caliper, a.k.a. micrometer. If you don’t have one available, various other sizing tools can be used to get a close estimate.

How much smaller Should an o-ring be?
To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.
What are the three dimensions used to determine o-ring sizes?
O-Rings have three different measurements: inside diameter, outside diameter, and cross-sectional thickness.
