O-rings and guide rings are both used on hydraulic cylinders, but they handle different tasks. O-rings are often the first choice for engineers because of their flexibility and performance in static ...

O-rings of five different kinds were tested using the iNano indentation system from KLA. The data on each is displayed in Table 1. A flat cylindrical punch (D= 100 µm) was used to measure the complex ...

For more than 60 years, engineers specifying seals and customers using them have accepted the arbitrary rule that the maximum amount O-rings will swell in most applications is a 25% change in volume.
