The WED bidirectional scraper has a combined scraper profile where the seal is provided with a scraping lip on the outside and a sealing lip on the inside.
The dimensions are interchangeable with a normal scraper housing.
The scraping lip is very flexible and compensates for misalignments of the rod. The sealing side has a stronger and longer lip to ensure the sealing performance, and to help the oil remain on the rod to back into the cylinder.
