KASTAS ROD SEALS K32
K32 is a two piece single acting rod seal which consists of one elastomeric sealing element specially designed with additional sealing lip and one thermoplastic back-up ring.
PRODUCT ADVANTAGES
• Superior sealing effect with the secondary lip
• High wear resistant
• Secondary sealing lip provides extra protection against the ingress of dirt particles.
• Improved sealing gap due to the active back-up ring
• Simple groove design
APPLICATION
Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery, mining equipment and standard cylinders.
