Item Information

The Z8 cylinder seal is a single-acting U-ring for pistons in pneumatic cylinders and valves. It is characterized by small axially installed dimensions. The standard range of the Z8 product series conforms to the cylinder diameters acc. to ISO 3320 and CETOP RP 52 P, RP 43 P and RP 53 P.
The Z8 product series is available in both Ultrathan® and rubber compounds. The Ultrathan® versions are characterized by extremely high resistance against wear and pressure peaks.

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Good sealing performance in extremely small assembly conditions.
• Good wear resistance.
• Low static and dynamic friction thanks to miniaturized design.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Easier installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed and undercut housings.

Range of application:
For use in pneumatic cylinders.
