How do you determine the squeeze of an O-ring?
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 .
How much compression should an O-ring have?
Compression should not exceed 3% of the O-ring diameter. Stretch for a smaller O-ring should not exceed 5%.
What is groove in O-ring?
Designing the parts of an application where o-rings will be applied is broadly termed “o-ring groove design”. In order to seal properly, the o-ring has to deform in the application by being compressed and stretched in any number of ways.
How far should an O-ring stick out?
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.
How do you choose an O-ring cross-section?
A thicker seal has more cross-section to withstand the movement and will theoretically handle more cycles than a thinner cross-section. A thicker seal will also have more stability in the groove and be less prone to rolling. However, thick seals will also have more friction in dynamic applications.

How much squeeze does an O-ring need?
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 O-ring material is best for high pressure?
High-durometer o-rings are better suited for higher pressures and are more resistant to extrusion. Hard material yields higher pressure required to force the o-ring into extruding. The only drawback to a high durometer is the decreased squeeze of the o-ring.
Can you use an O-ring without a groove?
Can O-rings be used in rectangular or non-circular groove patterns? This question comes up weekly, and the answer is a resounding “Yes!” however there are definite guidelines we want to follow. A non-circular face seal footprint might also be called a racetrack groove, a wandering groove or a custom plan view.
