YNF17311 Air Duct SANY SY135 Excavator Intake Hose

The YNF17311 air duct is manufactured for the SANY SY135 excavator, ensuring stable airflow from the air cleaner to the engine’s intake manifold. Built with high-grade reinforced rubber, this air duct offers strong resistance to suction collapse, pressure pulsation, heat, and long-term vibration during excavation operations.

Its OEM-matched design guarantees proper fitment, secure clamping, and airtight sealing, preventing dust and contaminants from entering the engine. This ensures fuel-efficient combustion and protects key components such as pistons, cylinders, and turbochargers from premature wear.

Replacing worn, cracked, or hardened air ducts with YNF17311 helps maintain engine power output, reduce downtime, and ensure stable machine performance. YNF air hoses are trusted globally by excavator repair workshops, machinery dealers, and fleet owners for their durability, stable supply, and excellent aftermarket value.
