K103 is a single acting double wiper ensuring that foreign particles are not introduced into the hydraulic cylinders. The lip is designed in a particular way that it reliably wipes off  the dirt but leaves a residual oil film on the rod.

PRODUCT ADVANTAGES
• Good wiping effect
• Wide range of dimensions
• No twisting in the housing
• Wiper lip reliably wipes away dirt and leaves a residual oil film on the retracting rod.
• Double lip makes additional protection to prevent the particles to enter into the cylinder
• Easy installation

APPLICATION
Construction machinery , fork-lift 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.

NOTES
K103 double wiper should be used in combination of suitable rod seals to avoid hydrodynamic pressure or pressure relieving bore between seal and wiper should be constructed to prevent the build up pressures (See section; Hydraulic Sealing Elements - Sample Designs).
