KASTAS K31 ROD SEAL

    KASTAS ROD SEALS K31

    K31 is a three piece single acting sealing set which consist of one elastomeric main sealing element with additional sealing lip, one special profile elastomer nitrile rubber that goes into the main sealing component and one thermoplastic back-up ring.

    PRODUCT ADVANTAGES
    • Able to work in high pressures
    • Superior sealing effect in low pressures
    • Easy assembly into closed grooves
    • Superior sealing effect with the secondary lip
    • Secondary sealing lip provides extra protection against the ingress of dirt particles.
    • Highly wear resistant
    • Improved sealing gap due to the active back-up ring

    APPLICATION
    Mining equipment, iron and steel industry, metal injection machines, scrap cutters, marine hydraulics, cranes and mobile hydraulics.

    INSTALLATION
    Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the rod seal must be oiled with system oil.
