Ensuring the longevity of your hydraulic system starts with clean air intake. The Hitachi 4434017 (also referred to as 4434017) is a critical component for maintaining pressure balance in the hydraulic tank of your Hitachi ZX200, ZX210, ZX240-3, and ZX330 series machines. Whether you are performing a routine service or a major engine rebuild, using an OEM-standard replacement breather filter prevents contaminants from entering your high-value hydraulic oil.

A clogged 4434017 breather filter is the most common cause. When air cannot escape or enter freely, pressure builds up, leading to seal failure in pumps and cylinders. Replace the 4434017 immediately if you notice tank bulging or unusual hissing sounds when opening the cap.
For excavators operating in high-dust environments (construction, mining), we recommend inspection every 250 hours and mandatory replacement every 500 hours to ensure the 4434017 remains effective.
Our parts feature an OEM-standard tri-metal structure and high-grade media, making them trusted by repair shops and equipment fleets worldwide for consistent performance.
