O'ring Groove Design As important as the o'ring seal itself is the groove that the o'ring seats into The groove must be designed to accommodate not just the o'ring size, but also its intended usage;Dovetail grooves are used to hold the Oring in place during installation or maintenance This groove design is relatively uncommon as it is expensive to machine and should not be used unless absolutely required The dovetail groove construction is only recommended for Orings with cross sections of 139 inch (3,53 mm) and largerORing Gland General Design Considerations ORing Squeeze Compression (ORing C/S) Gland Depth / (ORing C/S) • Face Seal 30% • Static Male/Female 15% • Reciprocating 10% • Rotary 010% ORing Installed Stretch (Groove Diameter) (ORing ID)(ORing ID) •

The groove design allows the Oring to be retained in the face seal during assembly and maintenance This is beneficial for special applications where the Oring has to be fixed by the groove eg a lid which opens regularly Bosstail The Oring is used for sealing straight thread tube fittings in a bossRubber Seals, Sealing Devices & ORing Seal Design AppleFace Seal Flange ORing Groove Design Chart Dovetail Flange ORing Groove Design Chart XRing and High Performance ORing XRing Seals and high performance ORing material groove design follows the same principals as basic ORing applications, although require even more attention to design adjustments for specific application environments
If you are designing a face seal, select the ORing with an inside diameter which will position the ORing on the side of the groove opposite the pressure Click here for more information on face seal groove design Note the ORing inside diameter for the next step Calculate the Seal Stretch Using Equation 1, calculate the installed seal stretch I am looking for some design recommendations on oring groove design to help retain an oring used in a face seal application With the standard rectangular groove the oring does not stay in the groove reliably and it can not be checked after assemblyMechanical / Heavy Duty Face Seals 'O' Ring Kits Circlip Kits Splicing Kits 'O' Ring Cord BARNWELL 'O' RINGS 3 effect a seal in a groove size of almost equal volume It is BARNWELL 'O' RINGS 4 The 'O' Ring The 'O' Ring or Toroidal Seal is a simple, versatile and economical
