DanaScraper 2 W470

This is the double wiper activated by two O-rings. Using two O-rings optimises the activation load on the profile ring. The wiper has a long service life, low friction and excellent wiping effect. In such an application, the wiper together with the housing are completely sealed, which prevents dirt pockets between housing and rod.
