The CS04-PD is a specialized high-pressure rod seal designed for compact hydraulic housings. Unlike the CS04-P, it features a unique angled backup ring specifically engineered to fit into narrower grooves without compromising performance. This O-ring energized seal provides exceptional preload, ensuring tight sealing across all pressure ranges up to 700 bar. Its anti-extrusion design and high-grade materials like HPU or FKM make it the ideal choice for short-stroke cylinders, clamping functions, and any application where axial space is strictly limited but high-pressure reliability is required.
• Narrow Groove Specialist: Optimized for compact seal housings with limited axial space.
• Angled Backup Ring: Distinctive profile design to prevent extrusion in tight spaces.
• 700 Bar High Pressure: Built to withstand extreme hydraulic system pressures.
• O-Ring Energized: Provides constant lip preload for superior static and dynamic sealing.
• Zero Reverse Leakage: Maintained integrity during high-frequency directional changes.
• Rapid Machining: Available in custom sizes with 24-hour delivery for urgent needs.
