About Excluder Wiper Seal
It is a double-acting dust seal composed of two scraper lips of different shapes installed back to back. It is installed in a groove together with the elastomer O-ring. The dust-proof function is completed by the sliding ring. The O-ring applies pressure to make the scraper lip close to the sliding surface and can compensate for the deformation of the piston rod.
Scrapes away contaminants from the retracted piston rod and protects the system from contamination.
On the medium side, prevents residual oil film on the extended piston rod.
