KASTAS K27 WIPER SEAL

    KASTAS DOUBLE WIPER SEAL K27
    PRODUCT ADVANTAGES
    K27 is a single acting double wiper ensuring that foreign particles do not penetrate into the hydraulic cylinders. The lip is designed in a particular way that it reliably wipes off the dirt but leaves a residual oil film on the rod.
    APPLICATION
    Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery and standard cylinders.

    INSTALLATION

    Generally, wiper can be easily ftted into the closed housing by deforming into a kidney shape. 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.

    NOTES

    K27 double wiper should be used in combination of suitable rod seals to avoid hydrodynamic pressure or pressure relieving bore between seal and wiper should be constructed to prevent the build up pressures (See section; Hydraulic Sealing Elements – Sample Designs). K27 wipers can be produced on request in FKM for special applications that require high temperatures.
