Description:

The RO9 is a double acting, O-ring energized, rotary seal. This low friction PTFE rotary seal is mainly used in applications with alternating pressures from one side of the seal to the other, such as in hose reels, swivel joints, rotating track rings and machine tool hydraulics. Can seal for both internal and external applications.

The machined grooves help to reduce friction and improve seal-ability.

Features:
  • Excellent chemical resistance
  • Excellent thermal resistance
  • Long sealing life
  • Simple fitting
  • Wear resistant
  • Low friction
  • No stick-slip
Applications:
  • Hose reels
  • Swivel joints
  • Rotating track rings
  • Hydraulic motors
  • Pivoting applications
  • And more
