PARKER C1 ROD SEAL

    C1 Rod Seal

    Descriptions

    The profile C1 rod seal meets the requirements of the manufacturers of hydraulic and
    pneumatic equipment for seals with the smallest possible housings. Although crosssections and heights are very small, the sealing performance is excellent.
    Extremely low friction is experienced because of the short contact of the sealing surface area. Back-up rings or brackets are not required because of the special design.
    Use in pneumatic equipment is only possible when consistent supply of lubricant
    such as oiled air is assured. For installation in non-lubricated pneumatic systems (dry
    air) we recommend our profile E5 which fits into the same housings.

    Features

    • Good wear resistance.
    • Easy installation.
    • High temperature resistance in case of
    suitable compound selection.
    • Excellent media resistance in case of
    suitable compound selection.
    • Suitable compounds available for
    special requirements of the chemical
    process industry.
    • Suitable compounds available for special requirements of the food processing
    industry.
    • Installation in closed and undercut
    housings.

    Range of application
    The profile C1 rod seal is especially recommended for plungers, piston rods, stems
    and valve lifters as well as for slowly operating pneumatic rotors (v ≤ 0,2 m/s).

    Operating pressure 1)

    Hydraulics≤ 160 bar

    (Definition see catalogue „Hydraulic Seals“, chapter „Rotary Seals“, introduction).

    1) Dependent upon cross-section and comp
    Compounds
    Standard: N3571, NBR compound (≈ 70 Shore A).
    For low temperatures: N8602, NBR compound (≈ 70 Shore A).
    For high temperatures: V3664, FKM compound (≈ 85 Shore A).
    Installation
    The profile C1 rod seals are manufactured over-sized on the external diameters in
    relation to the nominal dimensions. This ensures the required tight fit. Only after installation the sealing lip diameter will show the desired dimensions. Profile C1 can easily
    be snapped into the grooves.
    When choosing a seal for a particular diameter, it is best to select the one with the
    largest possible cross-section.
    Note: For nominal diameters ≤ 25 mm an open housing is recommended, according
    to the seals cross-section and the position of the groove (stuffing box installation).
