KASTAS K38 ROD SEAL

    KASTAS ROD SEALS K38

    K38 is a single acting rod seal with symetrical lips and an additional sealing lip which improves the leakage behaviour and at the same time, prevents the entry of dirt from the wiper side.

    PRODUCT ADVANTAGES
    • Superior sealing effect with the secondary lip
    • Low axial housing heights
    • Secondary sealing lip provides extra protection against the ingress of dirt particles
    • Easy assembly into closed grooves
    • Good sealing performance even at low pressures
    • Wide range of dimensions

    APPUCATION
    Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery, mobile hydraulics, standard cylinders, loading platforms and telescopic cylinders.
