PARKER AD WIPER SEAL

    AD Wiper Seal

    Descriptions

    The function of wiper rings is to prevent dust, dirt, grains of sand and metal swarf from
    penetrating into axially moving rods and plungers. Thus the development of scratches
    is largely prevented, guiding elements and seals are protected and the working life of
    the sealing system is extended.
    Profile AD consists of a PTFE wiper ring and an elastomer O-ring as a preloading element. It combines two functions: wiping against pollution from outside and a sealing
    function which reduces the residual oil film.
    The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes
    this product suitable for a wide range of applications, especially for aggressive media
    and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application profile.

    Features

    • Excellent wear resistance.
    • Minimal break-away and dynamic friction and no stick-slip tendency ensures
    uniform motion even at low speeds.
    • Good energy efficiency due to low friction.
    • High temperature resistance assured by
    suitable O-ring compound selection.
    • Adaptable to nearly all media thanks to
    high chemical resistance of the sealing
    ring and large O-ring compound selection.
    • Dimensions according to DIN ISO 6195,
    Type C or Type D.
    • Available in diameters from 4 to
    3000 mm.
    • Installation in closed and undercut
    housings.

    Range of application

    Operating temperature -30 °C to +100 °C 1)
    with FKM O-ring -30 °C to +200 °C
    Sliding speed ≤ 4 m/s

    1) With deviation from standard temperature range, please contact our consultancy service for adequate O-ring compound.
