A single-acting O-Ring energized rod seal with hydrostatic ventilation for use in dynamic applications. Prevents pressure build-up between seals in all service conditions. Low friction with no stick-slip, minimal break out force and high wear resistance. Recommended for use with a secondary rod seal in Turcon® material, together with a double-acting Excluder® or Scraper.

Double Delta® combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon® materials in. The double acting performance of the seal follows from the symmetrical cross section which allow the seal to respond to pressure in both directions. Initial contact pressure is provided by radial compression of the O-Ring. When the system pressure is increased the O-Ring transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.
