KASTAS K12 WIPER SEAL

    KASTAS METAL CASE DOUBLE WIPER K12

    K12 is a single acting double wiper ensuring that foreign particles do not penetrate into the hydraulic systems by their lip design, avoiding wear and damage to all the internal components including seals.
    PRODUCT ADVANTAGES
    Superior wiping performance
    Axially open, easy-construction groove
    Used in heavy conditions by the good mechanical properties of Polyurethane.
    Wiper lip reliably wipes away dirt and leaves a residual oil flm on the retracting rod.
    Space-saving design
    Double lip makes additional protection to prevent the particles to enter into the cylinder
    APPLICATION
    Construction machinery, fork-lift trucks, agricultural machinery,support cylinders and standard cylinders.

    INSTALLATION
    Wiper is pressed into axially open housings. Special equipment should be used during this process. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
