4695159 SEAL;OIL HITACHI for ZX350-7/6HK1T

Precision-Engineered for Fluid Containment and Contamination Exclusion – The Critical Barrier for Rotating Components.
The oil seal is a precision component that safeguards the integrity of rotating assemblies within your Hitachi equipment. This genuine oil seal is engineered to maintain a reliable barrier around shafts, preventing costly lubricant loss while blocking dirt, water, and abrasive particles from entering critical housings. Trust this seal to preserve fluid levels, protect bearings and gears, and ensure consistent system performance under pressure.

Advanced Lip Design and Premium Elastomer Formulation – Optimized for Long-Term Sealing Performance.
Manufactured from high-grade elastomers such as nitrile rubber (NBR), fluorocarbon (FKM), or polyacrylate—each selected for its specific application—this genuine oil seal features a precision-molded sealing lip with an integrated garter spring. This design ensures consistent radial pressure against the shaft, accommodating minor runout and thermal expansion. The rigid outer case guarantees a secure press-fit within the housing bore, delivering dependable sealing even under vibration, pressure spikes, and temperature extremes.

The High Cost of Seal Failure – Genuine Hitachi: Reliability Backed by Rigorous Testing.
A compromised or incorrectly matched oil seal leads to fluid leaks, contamination ingress, and accelerated component failure. Aftermarket seals often use inferior compounds that harden, swell, or lose their sealing force prematurely—jeopardizing equipment uptime and repair budgets. This genuine Hitachi component is manufactured to meet all original equipment specifications for lip geometry, material hardness, and dimensional accuracy. Protect your investment with the oil seal engineered specifically for Hitachi reliability.
