Safety Warning

Full Product Description

The self-retaining E8 pneumatics seal/wiper set for piston rods of pneumatic cylinders performs two functions: sealing and wiping. The split design of the sealing set enables optimum adaptation of the materials to the requirements of the individual component (wiper and seal).

• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Bi-functional element: seal and wiper.
• Good wear resistance.
• No risk of corrosion since the combined retainer and wiper part eliminates the need for additional wire circlips.
• Long service life due to coordinated geometries of the functional lips and compound selection.
• 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.
• Product geometry prevents dirt deposits at the front face of the cylinder.
• Identical housing for E7, E8, E9, EU, EF and ET.
• Installation in open housings.
• The coordinated geometries of the seal and wiper lips achieve favorable friction coefficients and long service life.

Range of application:
Mainly used for pneumatic cylinders.
