The flange seal FL06 is a symetric, spring energized seal for axial sealing applications. The

geometry is leant against profile PRS19.


  • Especially designed for pressure from inside.
  • Preload effected through V-spring which ensures high pressure on the sealing lips.
  • Excellent static and dynamic sealing performance.
  • Excellent sealing performance in low and high pressure ranges.
  • Simple mounting.
  • Compact and simple grooves.


Static sealing (e.g. flanges or fittings), chemical industry, Oil&Gas, aviation, rotary joints


inside diameter is limited to about 27mm minimum and cross section of 10mm maximum. For dimensions out of the limits production from 2 sides or special tools might be necessary!
