Specifications

The DK 109D profile is a double-acting seal for heavy mobile hydraulic services.
It consists of a sliding ring, confined by guides and energized by an elastomer profile. The relief of the friction ring allows its lubrication, increasing the life of the part.
- The slip ring cannot twist on itself.
- The slip ring cannot extrude.
- Improved friction ring lubrication.
The slip ring can be machined in various polyurethane formulations. See materials section.
