Description
The Hydraulic Cylinder Wiper Seal is a dual-acting, o-ring energized rod wiper/excluder with two distinct wiping tip geometries. The two lips work together to remove dirt from the rod, confine residual oil on rod extension, and allow oil to return to the cylinder. High-speed applications are possible with these Hydraulic Cylinder Wiper Seals, which reduce the possibility of stick-slip. They can provide excellent wear and scrape resistance, as well as a wide temperature and media compatibility range. If you are interested in it, please do not hesitate to contact us for more information.
