How do you size an O-ring?
How to Measure O-Rings
- Place the O-ring on a clean, flat, level surface.
- Determine the inside diameter by using a ruler to measure from one inner edge to another.
- Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner.
- Finally, measure the cross-section.
How are Viton O-rings measured?
O-rings are measured in millimeters. To measure the outside diameter, use a ruler or calipers to measure from one outer corner of the O-ring to the other outer corner. Measure cross section. Place the O-ring into a vernier caliper. Lightly clamp the jaws of the caliper onto the O-ring, but do not compress it.

O-rings are one of the simplest, yet most engineered, precise, and useful seal designs ever developed. They are available in various metric and inch standard sizes. Sizes are specified by the inside diameter and the cross section diameter (thickness).
How tight should O-rings 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.
Is WD 40 safe for O-rings?
It absolutely does not harm the o-rings. You’ll wear out the sprockets long before the chain. When you replace the sprockets (typically somewhere around 15-20K miles), you replace the chain too. In that period of time you are not going to harm your chain with WD-40.
