1. Key Features & Benefits
-
Genuine OEM Specification – Part number 3110625. Manufactured to Hitachi‘s original equipment standards for the EX1200-6, EX1200-5, and compatible 110–114 ton class excavators. This is a brand‑new, factory‑spec component – not an aftermarket substitute.
-
Critical Engine Air Intake Component – The air intake hose is an essential part of the engine‘s air intake system, responsible for channelling filtered air from the air cleaner assembly directly to the engine‘s intake manifold. It ensures a stable, uninterrupted supply of clean air for efficient combustion.
-
Heavy‑Duty Reinforced Rubber Construction – Manufactured from high‑strength reinforced rubber, specifically engineered to withstand the extreme conditions of large‑scale mining and construction operations. The robust construction resists high temperatures, intense vibration, and pressure fluctuations while maintaining reliable airflow performance.
-
Optimised Engine Performance – A properly functioning air intake hose is critical for maintaining combustion efficiency, engine power output, and overall engine longevity. Any crack, leak, or collapse in the hose can allow unfiltered air into the engine, leading to accelerated wear of internal components and reduced performance.
-
Direct Replacement for EX1200-6 / EX1200-5 – Designed specifically for Hitachi EX1200-6 and EX1200-5 large mining excavators. Mounting points and connection diameters match the original Hitachi specifications exactly – no modifications required.
-
Pre‑Shipment Visual Verification – Before packing, we send you detailed high‑resolution photographs of the actual unit (part number markings, hose condition, overall quality). You approve shipment – we never ship blind. Video inspection is also available upon request.
-
Fast Delivery – 5–7 working days lead time from our Guangzhou warehouse. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight.

3. Applications
The Hitachi 3110625 air intake hose is a critical engine component for EX1200-6 and EX1200-5 excavators used across the most demanding job sites:
-
Large‑Scale Open‑Pit Mining – EX1200-6 excavators weigh approximately 108–114 tons and are the backbone of copper, gold, iron ore, and coal mining operations. The air intake hose ensures a steady supply of clean, filtered air to the engine even in the extreme dust conditions of open‑pit mines. A cracked or perished hose can allow abrasive dust particles to enter the engine, causing rapid wear of pistons, rings, and cylinder liners – a repair that costs tens of thousands of dollars.
-
Quarrying & Aggregates – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries generate significant airborne dust. The reinforced rubber construction of this hose is specifically engineered to withstand high‑vibration, high‑dust environments, ensuring reliable engine protection shift after shift.
-
Heavy Civil & Infrastructure – Dam construction, highway cuts, tunnel portals, and large‑scale earthmoving projects. The hose‘s robust construction resists the temperature fluctuations and vibration common in these demanding applications, maintaining consistent airflow for optimal engine combustion and power output.
-
Equipment Rental Fleet – 110‑ton excavators are high‑value rental assets. A genuine new air intake hose ensures engine protection and predictable performance – preventing costly engine damage from unfiltered air ingress and avoiding mid‑contract breakdowns.
4. Maintenance Tips – Extend the Life of Your Air Intake Hose
A properly maintained air intake hose is essential for engine protection and performance. Follow these tips to protect your investment:
-
Inspect the hose regularly – Check the air intake hose for cracks, splits, soft spots, or signs of perishing. A cracked hose can allow unfiltered air and dust to bypass the air filter and enter the engine, causing accelerated wear of internal components. Pay particular attention to the connection points at the air cleaner and engine intake manifold.
-
Check hose clamps for tightness – Loose or corroded clamps can allow the hose to shift or disconnect, leading to unfiltered air ingress. Inspect and tighten all clamps to the correct torque specification during routine servicing.
-
Replace at the first sign of damage – Do not attempt to repair a cracked or split air intake hose with tape or sealant. These temporary fixes will fail under the high vibration and temperature conditions of mining operations. Replace the hose immediately with a genuine OEM component.
-
Keep the air intake system clean – When replacing the air intake hose, inspect the air cleaner housing and the engine intake port for accumulated dust or debris. Clean these areas thoroughly before installing the new hose to prevent contamination from entering the engine.
-
Replace the air filter at recommended intervals – A clogged air filter creates additional suction load on the intake hose, which can cause it to collapse or stress the connection points. Replace the air filter at Hitachi‑recommended intervals to maintain proper airflow and protect the intake hose.
-
Store spare hoses properly – Keep air intake hoses in a cool, dry place away from direct sunlight, ozone sources, and chemicals. Avoid storing them in a bent or compressed position, as this can cause permanent deformation.
Critical installation tip for the 3110625 air intake hose:
– Clean both connection points – before installing the new hose, thoroughly clean the air cleaner outlet and the engine intake manifold port. Remove any old sealant, dirt, or debris.
– Inspect the air filter housing – check the air filter housing for cracks or damage that could allow unfiltered air to bypass the filter.
– Use new hose clamps – always use new, high‑quality hose clamps when installing the air intake hose. Old clamps may have lost their clamping force or become corroded.
– Position the hose correctly – ensure the hose is not twisted or kinked during installation. A kinked hose restricts airflow, reducing engine performance and fuel efficiency.
– Torque clamps to specification – do not overtighten clamps, as this can damage the hose or the connection points. Tighten to Hitachi‘s recommended torque specification.
– Check for proper seating – after installation, verify that the hose is fully seated on both connection points and that there are no gaps or misalignments.
Warranty note: The warranty period is 3 to 6 months depending on product details. We do not provide warranty service for genuine original parts. Our value is delivered up front: genuine OEM components, new‑condition hose, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote aftermarket alternatives – ask our sales team.
The air intake hose is your engine‘s first line of defence against dust and contaminants. When it fails, abrasive particles can enter the engine and cause catastrophic damage.
