The CS09-D is a high-performance asymmetric double-acting composite rod seal, combining a low-friction PTFE gliding part with an elastic O-ring energizer. Designed to meet ISO 7425-2 standards, it ensures exceptional static and dynamic sealing without stick-slip. Featuring radial grooves for fast pressure activation and a chamfered design to prevent gap extrusion, it supports pressures up to 600 bar. Ideal for pressure intensifiers and control elements, the CS09-D provides high mechanical efficiency and exact positioning for both slow and quick reciprocating movements.
• Double-Acting Performance: Reliable sealing between pressurized spaces in both directions.
• ISO 7425-2 Compliant: Standard dimensions for easy integration and global replacement.
• Fast Pressure Activation: Integrated radial grooves ensure immediate sealing response.
• Zero Stick-Slip: PTFE material prevents crawling and ensures precise rod positioning.
• High Pressure Stability: Handles up to 400 bar standard, and up to 600 bar in special cases.
• Hole Crossing Capability: Specially designed to run over small, appropriately chamfered ports.
