Stepseal V

A single-acting, O-ring energized rod seal with hydrostatic pressure relief channel for dynamic applications. Prevents pressure trap between seals under all service conditions. Installed in closed grooves including grooves to ISO 7425, Stepseal V offers high sealing efficiency. It also gives, low friction with no stick-slip, minimal break out force and high wear resistance. Stepseal V is preferably used together with a secondary seal from the range of Turcon and Zurcon rod seals, together with a double-acting Excluder or Scraper.
