4412827 SEAL;DUST HITACHI for ZX200-3/4HK1T

Precision Contamination Barrier for Critical Systems – The First Line of Defense for Your Hydraulic Components.

This genuine Hitachi dust seal is precisely engineered to fit mating surfaces such as piston rods, shafts, and hydraulic cylinder heads, preventing dirt, mud, water, and abrasive debris from reaching critical seals and bearings . By keeping harmful contaminants out, it preserves lubrication integrity, reduces wear, and ensures reliable operation in even the harshest environments .

Advanced Elastomer Design with Optimized Lip Geometry – Built for Long-Term Sealing Performance.

Manufactured from high-grade, wear-resistant elastomers such as polyurethane or nitrile rubber (NBR), this dust seal features a precision-molded lip profile that maintains constant, tight contact with the moving surface while allowing smooth reciprocating or rotating motion . The material formulation resists ozone, UV exposure, and temperature extremes, retaining flexibility and sealing effectiveness over time . A precisely engineered interference fit ensures the seal stays securely in place, providing long-lasting protection without causing excessive friction or heat buildup .
