Turcon® AQ-Seal® 5 for Oil & Gas Applications - Trelleborg

Turcon® AQ-Seal® 5

  • High sealing effect in applications requiring media separation
  • Double security through the combination of low-friction special materials with elastomer seals
  • Operates in higher pressures
  • Improved sliding speed compared to the AQ-Seal®
  • Outstanding sliding properties, no stick-slip effect

The Turcon® AQ-Seal® 5 is a development of the proven standard Turcon® AQ-Seal®.

The seal profile of the Turcon® ring has been redesigned on both the dynamic and static sealing surface.

The AQ-Seal® 5 combines the benefits of a low-friction Turcon® slipper seal with the high sealing characteristics of an elastomer seal. It does this by incorporating a limited foot print X-Ring on the dynamic sealing face. This optimizes leakage control while minimizing friction. In addition, two O-Rings are used as energizing elements to optimize the pressure profile.

The Turcon® AQ-Seal® 5 is designed specifically for heavy duty and large stroke applications. It is recommended as a sealing element in double acting applications.
