Why Use an OEM-Compatible Air Hose?
The air hose in heavy equipment must handle high-flow volumes, heat exposure, and mechanical stress. A poor-quality hose may crack, leak, or collapse under engine vibration. YNF16722 offers extended routing capability and fits perfectly in Komatsu D275A-5 air systems, ensuring long service life and performance integrity.
