Single Point Contact Lip PTFE Seal

Single Point Contact Lip PTFE Seal

  • Thin dynamic lip design
  • Rotary service
  • Low friction seal material
  • Canted coil spring energized
  • Housing-mounted

The single point contact lip PTFE seal consists of a U-shaped seal jacket with a thin, low-profile dynamic lip geometry that creates a concentrated sealing zone for very low friction against the sliding surface. It is energized with a canted coil spring made from corrosion-resistant 316 stainless steel. The spring helps accommodate for small changes in the seal lip caused by wear, temperature change, or tolerance variations in the assembly. It also ensures effective sealing at startup and low pressures. This radial seal enables bi-directional assembly. It is best suited for housing-mounted applications and rotary service.
