Face seals need a consistent pressure around the entire oring to create a seal, but their groove diameters are not especially critical Face seals are a simple oring gland design and most adaptable to imprecise geometries, but require precise and solid attachment and checking over timeThe groove OD is calculated by adding twice the appropriate groove width The 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 ORingORing Groove Design Guides Expert Application Engineering Assistance Oring groove design guides offer default dimensional guidance on the most basic oring groove design applications The best orings are useless without the right groove design which becomes increasingly important the more demanding the application environment
