1. Description
A single-acting O-Ring energized rod seal for dynamic applications,step seals can be installed in closed grooves including grooves to ISO 7425. It offers high sealing efficiency, low friction with no stick-slip, minimal break out force and high wear resistance. Optimum sealing characteristics are achieved by installing in a tandem step seals arrangement together with a double-acting scraper. Available in bronze filled PTFE materials.
