Lathe Cut Gaskets

Lathe cuts are manufactured from a tube of rubber by inserting a mandrel into the tube and cutting the finished dimensions with a cutting tool while the mandrel is turning. ID’s range from 0.030” to 19.000”. Lathe cuts can be used as a bumper, sleeves, dampeners, static and radial seals, etc. They can be made out of any polymer group. In addition to the typical square or rectangular cross-sections, a number of special cross-sectional configurations are available within the standard size range.


  • Minimal or no tooling cost
  • Minimal process waste- no flash, parting lines, non-fills, centers, or webbing
  • No die-cut hour-glassing
  • Sizes can be easily adjusted
  • Suitable for standard and non-standard grooves
  • Wider sealing contact pressure and more consistent sealing pressure
  • Excellent physical properties
  • Performances are not sacrificed due to the extrusion process
  • Special curatives are used to ensure proper cross-linking
  • Easy to produce miniature sizes
  • Short lead-times
  • Best sealing choice when applications call for a static face seal
  • Flat, inner diameter adds stability and eliminates rolling and spiral failure                        

Darcoid and our manufacturing partners have expanded facilities for the production of lathe cut rubber seals. We use state of the art grinding equipment to finish outer surfaces to close tolerances. This lathe cut machinery is suitable for high speed, precision and large volume production.
