Komatsu PC100-5 Air Hose Description

The YNF17310 air hose (203-01-51221) is engineered for Komatsu PC100-5 excavators, delivering clean, stable airflow from the air filter assembly to the engine intake manifold. Made from high-strength, oil-resistant, reinforced rubber, this hose maintains structural stability under suction pressure and heavy vibration.

The hose is designed with OEM-matching curvature and thickness, ensuring proper fitment, airtight sealing, and long-lasting performance. It helps prevent dust, debris, and unfiltered air from entering the engine—protecting pistons, cylinders, and turbo components from premature wear.

Replacing cracked or hardened air hoses with YNF17310 ensures a cleaner air supply, improved combustion efficiency, and reliable engine power output. YNF hoses are preferred by maintenance centers, fleet operators, and distributors due to their durability, stable availability, and cost-effective aftermarket value.
