PARKER C2 PISTON SEAL

    C2 Piston Seal

    Descriptions

    The profile C2 piston seal meets the requirements of the manufacturers of hydraulic
    and pneumatic equipment for seals with the smallest possible housings. Although
    cross-sections and heights are very small the sealing performance is excellent.
    Extremely low friction is experienced because of the short contact to the sealing surface area. Because of the special design, back-up rings or brackets are not required.
    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 E4 which fits into the same housings.

    Features

    • Good wear resistance.
    • 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.
    • 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
    Especially recommended for pistons in hydraulic and pneumatic cylinders.

    Operating pressure 1)

    Hydraulics≤ 160 bar
    Pneumatics≤ 16 bar

    Operating temperature

    Hydraulics-25 °C to +100 °C
    Pneumatics-25 °C to +80 °C
    Sliding speed≤ 0.5 m/s

    1) Dependent upon cross-section and compound.
    Compounds
    Standard: N3584, NBR compound (≈ 85 Shore A).
    For low temperatures: N8613, NBR compound (≈ 80 Shore A).
    For high temperatures: V3664, FKM compound (≈ 85 Shore A).
    Installation
    The profile C2 piston seals are manufactured undersized in relation to the nominal dimensions. Only after installation will the sealing lip diameter have the desired dimensions. This lip seal may easily be snapped into the grooves. Care should be taken that
    the seals are not pulled over sharp edges.
    In the case of double-acting pistons, pressure peaks should be avoided. In such
    cases, sealing elements with larger cross-sections or other profiles with header rings
    should be used.
