How to calculate o-ring stretch

WebO-Ring Basics; Dimensional Considerations; Inside Diameter. 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 piston applications. WebO-rings with smaller cross sections are squeezed by a higher percentage to overcome the relatively higher groove dimension tolerances. In static applications the recommended squeeze is usually between 15-30%. In some cases the very small cross sections can even be squeezed up to 30%. In vacuum applications the squeeze can even be higher.

WebStep 3. Find your o-ring's squeeze amount in inches by subtracting the gland depth from cross-sectional diameter with a calculator. For example, if your o-ring's cross-sectional diameter is 1.25 inches and its gland depth is 1.20 inches, subtract 1.20 from 1.25 to determine that the o-ring is able to squeeze out a total of .05 inches. WebA stretch greater than 5% on the O-ring I.D. is not recommended because it can lead to a loss of seal compression.
