Product Overview
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.
