KASTAS ROD SEALS K33
K33 is a single acting rod seal designed to have inner lip shorter than the outer lip and additional sealing lip which improves the leakage behavior and, at the same time, prevents the penetration of dirt from the wiper side
PRODUCT ADVANTAGES
• High wear resistant
• Superior sealing effect with the secondary lip
• Secondary sealing lip provides extra protection against the ingress of dirt particles
• Wide range of dimensions
• Simple groove design
• Easy assembly into closed grooves
APPLICATION
Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery, loading platforms and standard cylinders.

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 sealing element must be oiled with system oil.
