KASTAS K701 ROD SEAL

    KASTAS ROD SEALS K701

    K701 is a two piece single acting rod seal which consists of a PTFE u-ring with metal spring as a tension component.

    PRODUCT ADVANTAGES
    • Superior static and dynamic sealing effect by the metal spring
    • High resistance to chemicals and temperature changes
    • Low friction, free of stick-slip
    • High sliding speed
    • Long service life
    • Good dry running conditions
    • Can be sterilized
    • Low static and dynamic friction values

    APPLICATION
    Hydraulic and pneumatic cylinders, hot water valves, pumps, hot steam valves, food processing, chemical and medical technology.

    INSTALLATION
    K701 is can be assembled into open and closed grooves. It is very important that the installation tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

    NOTES
    Depending on the PTFE material application values and their resistance can change. The permissible sealing gap values of K701 spring loaded rod seal is given in the below table.
