The Zurcon Scraper DA 22 is a double-acting polyurethane wiper for closed groove installation.

The scraper lip is designed in a particular way that it reliably scrapes off the dirt but leaves a residual oil film on the rod, which is required for correct operation. The radial squeeze is sufficient to remove particles, dust and water.
