Hexagonal type rod wiper seal is a special external dust-proof seal designed for hydraulic piston rods. Different from conventional round wiper seals, it adopts a hexagonal outer profile, which effectively prevents the seal from rotating inside the installation groove during reciprocating movement. This unique structure keeps the scraping lip steadily attached to the rod surface, improving the reliability of dust removal.
Made of high wear-resistant polyurethane, the hexagonal rod wiper can scrape off dust, mud, sand and metal debris on the piston rod before contaminants enter the hydraulic cylinder. It avoids abrasive particles damaging rod seals and guide rings, and extends the service life of the whole hydraulic sealing system. The material features good low-temperature toughness and aging resistance, adapting to harsh outdoor working conditions.
The hexagonal outer shape locks the seal firmly in the groove, preventing displacement and twisting. It fits standard mounting grooves and supports quick installation and replacement. This wiper seal is widely used in construction machinery, agricultural equipment and heavy-duty hydraulic cylinders.
As a critical protective sealing component, the hexagonal type rod wiper seal reduces hydraulic cylinder failures and maintenance costs. It works together with rod seals to form a complete sealing protection system for reciprocating piston rods.
