Rotary seals

424 (Rotary seal, double acting)

The seal AF-424 has been specifically designed to seal swiveling or rotary applications. This double acting seal is used for internal sealing (rod).
Lower friction compared to AF-423, and able to handle higher pressure.



  • Delivered with notches by default (with two or four notches on either side), but is also available without
  • Low friction
  • High durability
  • Very low stick-slip tendency, even at low velocity
  • Two-part composition, consisting of a dynamic glide ring and an O-ring



  • Operation pressure: Up to 40 MPa (400 bar)
  • Velocity: Rotating up to 4 m/s (uni- and bi-directional
  • Temperature: -40°C to 200°C
