PTFE Rotary Lip Seals

Carbon Graphite Rotary Shaft Seal by Advanced EMC TechnologiesPTFE Shaft Seals

Advanced EMC introduced our FluoroSeal™ PTFE lip seals in the early 1990s. The seals were designed to bridge the gap between conventional elastomeric lip seals and mechanical face seals. Hostile environments such as extreme temperature, aggressive media, high surface speeds, high pressures, and lack of lubrication forced the designer to specify expensive face seals which were more complicated mechanical face seals.

FluoroSeal PTFE lip seals provide the designer a significant improvement in performance over elastomeric lip seals at a much lower cost than the mechanical face seal. FluoroSeal PTFE rotary lip seals solve frictional heat problems in high speed rotary applications, which are not addressed by conventional elastomeric shaft seals.

PTFE Rotary Shaft Seals GuideWe exceed the performance of the conventional rubber lip seals in the following areas:

  • Available in hydrodynamic, plain and multi-lip configuration
  • Wide range of materials to suit the demands of the application
  • Low volume requirement can be constructed from machined shells (so there are no tooling charges)
  • High volumes can be manufactured from pressed shells reducing unit costs

FluoroSeal PTFE Lip Seals solve difficult sealing applications which cannot be addressed by conventional elastomeric lip seals. We exceed the performance of the conventional rubber lip seals in the following areas:

  • Much lower friction which generates less torque
  • Less frictional heat and requires less power
  • Reduced breakout friction
  • Much lower friction which generates less torque
  • Less frictional heat and requires less power
  • Reduced breakout friction
  • PTFE lip seals work well in petroleum oils and  fuels; ozone chemical applications; solvents (MEK, acetone, xylene); and weather extremes, but not highly fluorinated greases or oils
  • Capable of pressures to 500 PSID (6Mpa)
  • Large diameter and custom design capability
  • Conveyor Rollers
  • Electric Motors Rolling Stock
  • Generators, Compressors, Vacuum Pumps
  • High Performance Vehicles
  • Chemical Processing Equipment
  • Pumps, Mixers, Agitators, Blenders
  • Pharmaceutical
  • Food Processing
  • Power Steering
  • Dust/dirt Excluders
  • Off Road Vehicles
  • Radar Equip
  • Paper Mills
