The CP08-DS is a premium asymmetric composite PTFE piston seal engineered specifically for heavy-duty and high-pressure hydraulic applications. Functioning as a high-performance Step Seal or Glyd Seal alternative, it features a massive profile ring and a robust elastic energizer for maximum stability and pressing force. This CNC-machined coaxial seal handles pressures up to 600 bar without stick-slip or gap extrusion risk. Ideal for large-diameter reciprocating pistons, it ensures precise positioning and exceptional mechanical efficiency even after prolonged standstills. Whether in mobile hydraulics or heavy industrial cylinders, the CP08-DS provides reliable, low-friction sealing under extreme operating conditions.
· Heavy-Duty Design: Massive profile ring ensures high stability in the most demanding environments.
· High Pressure: Optimized for standard 400 bar, withstanding special cases up to 600 bar.
· Coaxial Sealing: Premium Step Seal / Glyd Seal type construction for bi-directional strokes.
· CNC Machined: Precision turning process allows 24-hour delivery on custom large-diameter orders.
· Anti-Extrusion: Reinforced chamfer design significantly reduces gap extrusion risk under high load.
· Low Friction: Eliminates stick-slip for smooth running and exact positioning of heavy cylinders.
· Fast Activation: Radial grooves ensure instantaneous pressure response and sealing force.
· Wear Resistant: Specialized massive profile minimizes relative motion and extends service life.
· Thermal Stability: Non-sensitive to damage from air-in-oil effects or wide temperature ranges.
