The Z8 piston rod seal represents a specialized sealing solution engineered for the most demanding pneumatic applications. Designed as a single-acting U-cup lip seal, the Z8 series excels in compact pneumatic cylinders, valves, and actuators where installation space is limited yet sealing performance cannot be compromised. Its short axial design ensures seamless integration into standard grooves conforming to ISO 3320 and CETOP RP 52 P specifications, making it a drop-in replacement for many OEM and aftermarket systems.
What sets the Z8 piston seal apart is its optimized lip geometry, which minimizes both static and dynamic friction while maintaining a reliable sealing interface. This low-friction characteristic translates directly into smoother piston rod movement, reduced heat generation, and extended component service life. Whether your system operates with lubricated compressed air or requires oil-free functionality, the Z8 delivers consistent performance after initial lubrication, effectively reducing wear and preventing leakage even under pressure fluctuations up to 16 bar.
Durability is another cornerstone of the Z8 series. Available in multiple high-performance materials including NBR (standard, -20°C to +100°C), TPU (Ulthathan®, -35°C to +80°C), and FKM (-25°C to +200°C), this seal accommodates a broad range of temperature and media compatibility requirements. The TPU variant offers exceptional abrasion resistance, while FKM provides superior chemical and high-temperature tolerance for more aggressive environments.
Installation is straightforward thanks to the seal’s flexible lip construction, which allows for simple pull-over mounting even in closed or undercut housings. This reduces assembly time and minimizes the risk of damage during installation. With maximum operating speed of 1 m/s, the Z8 is well-suited for both short-stroke and moderate-speed pneumatic cycles.
For engineers and maintenance professionals seeking a reliable, space-efficient sealing solution, the Z8 piston rod seal offers proven performance, material versatility, and long-lasting durability. It is a smart choice for improving pneumatic system efficiency and reducing downtime.
Choose Z8 – where compact design meets uncompromising reliability.
