How You Benefit From The KC Sealing System

KC Multi-Ring®Gasket Design

  • Evenly distributes clamping force around entire flange face
  • Reduces/eliminates flange distortion
  • Requires as little as 50% bolt torque as conventional designs
  • Engineered to fit each different pipe/flange style
  • Available in these styles:
PVDF Universal New ANSI
PVDF ring – BCF/IR flange adapters Old ANSI
PVDF ring – socket fusion flange adapters Polypro & others contact factory
Schedule 10 FRP Ducting
  • Only one torque value required for same size flange in PVDF, Schedule 10, and New  ANSI styles in like material
  • Gasket styles can be cut and molded from any material:
Expanded PTFE
Expanded PTFE (densified)
FPM (Fluorine Rubber)

Other sheet or roll material

AC Flange Rings

Available for both new and existing construction

  • Engineered to direct the clamping force towards the pipe ID, not the flange adapter OD
  • Provides a positive seal at the inner ring on a KC Multi-Ring® gasket
  • Minimizes gasket surface area contacted by medium
    (Contamination from gasket is proportional to gasket surface area)
  • Reduces the cavity at flanged joints
  • Available for plastic piping
  • Thermoplastic coating is more resilient and less brittle than PVDF
    When an AC flange is dropped, the coating dents
    Dents can be “smoothed out” in the field with a heat gun
  • Independent Finite Element Analysis confirms KC Multi-Ring®’s lab results which support all of the patent claims.
