The flange seal FL07 is a symetric, spring energized seal for axial sealing applications. The

geometry is leant against profile PRS19C.


  •  Especially  designed  for  pressure  from  outside.
  •  Preload effected through Helicoil-spring which ensures high pressure on the sealing lips.
  •  Excellent  static  and  dynamic  sealing  performance.
  •  Excellent sealing performance in low and high pressure ranges.
  •  Wide application ranges – Especially suitable for gas and vacuum applications.
  •  Simple mounting.
  •  Compact  and  simple  grooves.


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


The inside diameter is limited to about 15mm minimum. The cross section should not exceed 10mm. For dimensions out of the limits production from 2 sides or special tools might be necessary!
