100 SERIES - Spring Energized Static Seals

100 Series seals are helically wound, flat ribbon, metallic spring energized polymer seals.

RECOMMENDED APPLICATIONS:

  • Static Rod and Piston Seals
  • Static Internal and External Pressure Face Seals
  • Reverse Pressure to 100 psi
  • Vacuum to 3,000 psi with a standard heel design
  • 10,000 psi with the extended heel and/or backup rings
  • Temperatures from -450ºF to 650ºF
  • Can be installed in closed glands based on seal diameter and cross-section
Seal samples

The 100 Series helical spring design is intended for static applications due to the high unit load. It can be used in very slow or infrequent dynamic conditions when friction and wear are secondary concerns to positive sealing. The 100 Series seal design produces an evenly distributed load across each individual band. Polymer Concepts' manufacturing maintains minimal gaps between coils. This tight spacing provides continuous load, reducing potential leak paths. This tight spacing, combined with high unit load, makes this series well suited for vacuum and cryogenic applications.

DESIGN FEATURES RECOMMENDED APPLICATIONS
  Seal diagram Standard heel, radius leg design High pressure, low temperature static or dynamic seals where friction is secondary to sealing and any extrusion gap is less than .004". Use GW gland width  
Seal diagram Heel plus design Same as standard but use when an extrusion gap is less than .008". Use GW1 gland width
Seal diagram Standard leg design with high modulus back-up ring Same as heel plus design but with an extrusion gap of less than .012. Use GW2 gland width
Seal diagram Cammed heel plus design with high modulus back-up ring Single camming action to close off the O.D. extrusion gap under pressure. Use GW2 gland width
Seal diagram Standard heel plus design with dual cam, high modulus back-up rings Same as cammed heel plus design but with dual camming action for multiple extrusion gaps found in two-piece hardware design. Use GW2 gland width
Seal diagram Skived I.D. or O.D. design When a shearing action of the media off the dynamic surface is desired. Use GW gland width
Seal diagram Inside or outside pressure seals Static high pressure or slow rotary when sealing takes priority over friction. Reference face seal gland dimensions
Seal diagram Hardware contained rod or ball valve seal Seal solution when the dynamic hardware disengages the seal under pressure. Consult the factory for gland design
Seal diagram Flanged heel design Radial seal for slow rotary or oscillatory motion, less than 50 ft./min. at high pressure. Consult the factory for detail gland dimensions
