A noncircular face seal footprint might also be called a racetrack groove, a wandering groove or a custom plan view When using an Oring, the main design consideration is the corner or smallest radius (shown "r" in diagram) The inside radius should be at least three times the Oring cross sectional diameter In a perfect world, six times greater is even better10 ORING SEALS – THEORY AND DESIGN PRACTICES Theory An oring seal consists of an oring and a properly designed gland which applies a predictable deformation to the oring The gland is basically a groove dimensioned to a certain height "H" and width "W" (Figure 1) to allow a fixed compression of the oring when the gland flanges make metal to metal contact It is alsoThe recommended gland depths for QuadRing® Brand seal and ORing face seal applications are the same as for radial applications Recommended gland depths can be found in the QuadRing® Brand seal tables and for an ORing However, the orientation of a face seal groove is axial instead of radial In an application where there is direct contact between the mating surfaces, such as
