K09

K09 is a single acting wiper ensuring that foreign particles are not introduced into the hydraulic systems , avoiding wear and damage to all the internal components including seals.

PRODUCT ADVANTAGES
•    Very good wiping performance
•    No twisting in the housing
•    Specially design to prevent big particles to go into the system
•    Wide range of dimensions
•    Used in heavy conditions by the good mechanical properties of PU material
•    Secure seating into the groove

APPLICATION
Construction machinery , forklift-trucks , injection moulding machines , agricultural machinery and standard cylinders.

INSTALLATION
Generally , wiper can be easily fitted 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.
