Rotary Seal – ID – OR Energized



Low friction

Double-acting applications

High-temperature resistance

Low wear

Extrusion resistant

Compatible with a wide range of media

Available in diameters up to 2100 mm

High abrasion resistance


The 415 series rotary seal is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.

Typical applications include:

  • Rolling Mills
  • Hydraulic Motors
  • Agricultural Hydraulics
  • Mobile Hydraulics
  • Wind Energy
  • High Pressure Valve Stems
  • Rotary Actuators
  • Rotary Swivels

The 415 series rotary seal features custom blended PTFE-filled compounds providing ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE with Bronze filler, or PTFE filled with Glass-Moly + NBR. The temperature range of the seal can be increased by selecting an FPM O-Ring in place of the standard NBR O-Ring.
