The Z9 rod seal is a single-acting U-ring with interference fit on the outer diameter for sealing piston rods in pneumatic cylinders and valves. It is characterized by small axial installation dimensions. The standard range of the Z9 product series conforms to the cylinder diameters according to ISO 3320 or CETOP RP 52 P, RP 43 P and RP 53 P.

• Due to application-optimized geometry and compounds suitable for use in lubricated as well as in oil-free air (after initial lubrication on assembly).
• Good wear resistance.
• Low static and dynamic friction thanks to miniaturized design.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• 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.
