HWC Wear-resistant Wiper Seal is designed to provide reliable protection for hydraulic cylinders operating in harsh and highly contaminated environments. Its specially designed wiper lip maintains close contact with the piston rod surface, effectively removing mud, dirt, and other heavy contaminants during reciprocating movement.
The outer lip fits tightly against the housing groove to help prevent contaminants from entering the cylinder. HWC combines excellent wear resistance, low compression set, and resistance to extrusion, ensuring long-term, reliable performance. It is an ideal scraper wiper seal for mining equipment and other hydraulic machinery exposed to severely contaminated environments.
