In order to seal properly the o-ring has to deform in the application by being compressed and stretched in any number of ways. The design of the groove where the o-ring sits plays a major role in how the o-ring performs its sealing role. Calculate the Seal Stretch.
Seal Design Seals are divided into three primary categories: Static Face or Flange, Static Radial type, and Dynamic Radial type. Using Equation 1, calculate the installed seal stretch.
Design Guide These percentages are typical recommendations based on a standard groove. Face or Flange type seals have no clearance gap, but consist of a groove cut into one flange with a flat mating flange bolted together to give a surface Using Equation 1, calculate the installed seal stretch.
Please consult our Application Engineers for design assistance specific to each application.

These square-profile O-rings have flat edges on all four sides, so they cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections. The groove root diameter and width will be found under their respective columns.
Wear sleeves . Calculate the Seal Stretch. Designing the parts of an application where o-rings will be applied is broadly termed "o-ring groove design". GO TO PRODUCT FAMILY .
