Boom Seal Kit Description
The 440-00355AKT boom cylinder seal kit is engineered for Doosan DX225 excavators, providing a complete sealing solution for the boom hydraulic cylinder. It is widely applied in maintenance and repair operations where sealing integrity is essential to ensure stable boom movement and machine performance.
Each component, including piston seals, rod seals, wiper seals, and O-rings, is manufactured under strict quality control standards. High-grade materials such as polyurethane and NBR are adopted to ensure excellent resistance to high pressure, abrasion, and hydraulic oil. As a result, consistent sealing performance is maintained even under harsh working environments such as construction and mining.

With YNF Machinery, bulk supply is supported, helping B2B buyers reduce downtime, maintain inventory efficiency, and improve overall profitability in local markets.
