Commercial Description

This single-acting O-Ring energized rod seal is made of Turcon® and provides high static and dynamic sealing results. Can be installed together with other seals in a tandem configuration for advanced static and dynamic tightness. The Turcon® Stepseal® 2K offers high extrusion resistance, low friction with no stick-slip, minimal break out force and high wear resistance.

Installation & Handling

Rod seals must exhibit no dynamic leakage to the atmosphere side under all operating conditions and must be statically completely leak tight when the machine is at a standstill. Furthermore, they should achieve a high degree of mechanical efficiency through low friction and be easy to install in small grooves. Costs and service life must meet the high expectations of the operator. The rod seal Turcon® Stepseal® 2K comes closest to satisfying these ideal demands. Since the first Stepseal® was patented, Trelleborg Sealing Solutions has maintained the series as technically outstanding through continuous innovation. Turcon® Stepseal® 2K marks the latest development. The introduction of Stepseal® made it possible to arrange several seals in sequence thus allowing statically and dynamically tight double-acting tandem seal configurations to be created while avoiding disturbing build-up of intermediate pressure. The single-acting seal element is made of high-grade Turcon® materials with outstanding sliding and wear resistance properties. It is installed according to ISO 7425-2 and Trelleborg Sealing Solutions standard grooves, using an O-Ring as energizing element.
