Features & Benefits


  • Maximum stroke/diameter ratio.
  • Broad range of fabrics and elastomers.
  • Differential pressure capability (limited by beaded flange) is normally to 150 psi.
  • Pressure applied from one direction only.
  • Must be formed into convoluted shape during assembly
  • Beaded flange assists in assembly.
  • Seal enhanced by bead, which spreads under pressure in a properly dimensioned hardware groove.
  • Outside flange diameter is generally less than that of a flat flange design.
