U‑Cup DDI are high-performance static seals crafted from an elastomeric U-shaped lip design with dual backup lips (DDI style) for robust sealing in hydraulic and pneumatic cylinders. The concentric lips create effective fluid retention at low pressure with backup support to resist extrusion under high pressure. Adaptable and easy to install, these seals offer excellent wear resistance, chemical compatibility, and durability for reliable performance in demanding industrial environments.
