A single-acting O-Ring energized piston seal for dynamic applications, the Turcon® Stepseal® 2K provides excellent static and dynamic sealing results. This advanced seal is stick-slip free, suits a wide range of application temperatures and demonstrates excellent abrasion and extrusion resistance. Optimum sealing characteristics are achieved by installing in a tandem arrangement with a double-acting scraper.
The Stepseal® 2K is a single-acting seal element consisting of a seal ring of high-grade Turcon® materials and an O-Ring as energizing element. The Stepseal® 2K was originally developed and patented by Trelleborg Sealing Solutions as a rod seal. Due to its outstanding properties, however, it is equally well suited as a singleacting piston seal where high demands are made on positional accuracy and free movement.
