HWBA Waterproof Wiper Seal is a single lip wiper seal made from high-hardness, wear-resistant polyurethane. Its specially designed sealing lip provides excellent scraping performance, helping prevent water, dust, and other contaminants from entering hydraulic cylinders in demanding operating environments.
HWBA wiper seal maintains effective waterproof performance even when the piston rod is subject to eccentric movement. Its low-friction design and strong resistance to extrusion make it particularly suitable for hydraulic cylinders exposed to heavy side loads, including mining hydraulic supports.
