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

Turcon® T-Seal

  • Good static and light-duty dynamic sealing effect
  • Excellent resistance to rolling within the groov
  • Excellent extrusion resistance
  • Provides bidirectional sealing
  • Preferred option for media separation, such as fluid/gas or fluid/fluid
  • Available in flash-free version
  • Sizes to suit all O-Ring grooves including AS-568 and ISO-3601 seal sizes

Turcon® T-Seal consists of a T-shaped elastomer sealing element supported by Turcon® or Zurcon® Back-up Rings on both sides. This combination results in a stable seal, the semi-circular lip configuration ensuring positive sealing. The side flanges, which form the seal’s base offer excellent resistance to rolling and act as an effective platform to position and energize the anti-extrusion rings.

The one or two Back-up Ring widths offer especially good protection against extrusion. This is due to the additional material volume of the Back-up Rings compared to zero Back-up Ring widths.
