Dovetail ORing Gland Design In a dovetail oring gland application the oring squeeze is primarily axial in direction, where a valve exerts force on the top and bottom of the orings surfaces Typically used in static or slow moving applications the dovetail orings gland purpose is to properly hold the oring in place during machine operationThere are two types of radial designs 1 Male or Plug the Oring groove is located on a plug which is inserted into the housing or cylinder (fig 123) 2 Female or Tube the Oring groove is located in the housing or cylinder and a tube is installed through the Oring lD (fig 124) Male or Plug Seal design is based onThe squeeze or rate of compression is a major consideration in Oring seal design and differs per Oring application design Orings with smaller cross sections are squeezed by a higher percentage to overcome the relatively higher groove dimension tolerances In static applications the recommended squeeze is usually between 1530%
