Turcon® AQ-Seal® for Oil & Gas Applications - Trelleborg

Turcon® AQ-Seal®

  • Combines the benefits of a low-friction Turcon® slipper seal with the high sealing characteristics of an elastomer seal
  • High sealing effect in applications requiring media separation, fluid/fluid or fluid/gas
  • Low gas permeation rate
  • Double security through the combination of low-friction special materials with elastomer seals
  • Simple groove design, small installation space, interchangeable with Turcon® Glyd Ring®, Turcon® Glyd Ring® T and Turcon® Stepseal® 2K
  • Capable of operating successfully at higher pressures and sliding speeds
  • Outstanding sliding properties, no stick-slip effect

The Turcon® AQ-Seal® is a double-acting seal consisting of a seal ring of high-grade Turcon® material, an X-Ring and an O-Ring as energizing elements. The Turcon® seal ring together with the X-Ring perform the dynamic sealing function, while the O-Ring performs a static sealing function.

The AQ-Seal® is supplied as standard with radial notches on both sides. These ensure direct pressurizing of the seal under all operating conditions.
