K107 is TPU double wiper with a static sealing lip as an addition to the wiping lip. The dynamic lips of K107 double wiper are designed with a radius in order to optimize the oil film on counter running surface and the seal geometry is designed to relief hydrodynmaic pressure in the system.

Advantages

Superior wiping performance
Build-up of hydrodynamic pressure is avoided with notch design
Thing oil film due to double lip design
No twisting in the housing
Used in heavy conditions by the good tear and rupture properties of PU material
Leakage preventing exterior static sealing lip design
Easy installation

Area of Application
