Full Product Description

The E4 piston seal is a lip seal specifically developed for use in pneumatics. The dimensions of the standard series correspond to the cylinder diameters according to ISO 3320, CETOP RP 52 P, RP 43 P and RP 53 P.
The E4 piston seal is available in both Ultrathan® and rubber compounds. The Ultrathan® versions are extremely resistant 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).
• Suitable for cylinders with dead-center cushioning.
• Good wear resistance.
• Long service life thanks to application-optimized compounds.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Easier installation.
• Suitable for fully automatic installation
• Assembly on one-part piston is possible.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed housings.
• Special seal geometry ensures optimal function even in case of flow-controlled exhaust air.

Range of application:
Mainly used for pneumatic cylinders.
