Turcon® Stepseal® 2K for Oil & Gas Applications - Trelleborg

Turcon® Stepseal® 2K

  • High static and dynamic sealing effect
  • Eliminates the build-up of disruptive intermediate pressures between seals
  • High extrusion resistance, to suit wide hardware clearances
  • High-frequency operation
  • Low friction, increasing performance and working life
  • Stick-slip-free starting, no sticking even after extended periods of rest
  • High abrasion resistance, maximum operational reliability
  • Compatible with virtually all media
  • Suited to mineral oil-based hydraulic fluids, flame retardant hydraulic fluids, environmentally-safe hydraulic fluids (bio-oils), water and other media
  • Simple installation without seal edge deformation
  • Unidirectional seal

Turcon® Stepseal® 2K enhances sealing efficiency with better extrusion resistance giving superior leakage control and allowing larger hardware tolerances, making cylinder production more economic. It is also more uniform, showing low-friction characteristics throughout an extended life and even during the run-in period when friction forces can have the greatest effect on hydraulic seals.

Turcon® Stepseal® 2K can be matched to specific mating surfaces and media. Seals can be specified to meet the precise degree of extrusion and abrasion tolerance required for an application.
