The CP08-D is a high-performance asymmetric composite PTFE piston seal, widely known as a Step Seal or Glyd Seal type coaxial sealing solution. It features a low-friction gliding part and an elastic preload element, making it ideal for smooth-running hydraulic cylinders. This CNC-machined seal supports pressures up to 600 bar and eliminates stick-slip even at slow speeds. With its unique radial grooves for fast pressure activation and a chamfered design to prevent gap extrusion, the CP08-D ensures exact positioning and high mechanical efficiency. It is a durable, cost-effective alternative for heavy-duty reciprocating pistons in various industrial environments.
· Coaxial Sealing: Advanced asymmetric composite design (Step Seal / Glyd Seal type).
