AIR HOSE

The 550 199 04 AIR HOSE (55019904, 550-199-04, AIR HOSE 55019904) is a mining-duty pneumatic hose engineered for Sandvik drilling rigs, ROC series machinery, and underground jumbos. The 550 199 04 AIR HOSE delivers consistent high-pressure air to drilling controllers, pneumatic tool circuits, brake systems, and auxiliary actuators used in mining and tunneling operations.

This 550 199 04 AIR HOSE is constructed using abrasion-resistant, oil-resistant, and vibration-resistant hose materials capable of withstanding extreme dust, hydraulic mist, temperature fluctuations, and mechanical shock. Catalog identifiers 55019904 and 550-199-04 are widely used across OEM and aftermarket spare parts references.

The 550 199 04 AIR HOSE maintains stable pneumatic supply for drilling control valves, actuator systems, and machine support equipment. Consistent airflow ensures smooth drilling control, reliable feed behavior, and reduced downtime in mining, tunneling, and quarry operations.

Inspect the 550 199 04 AIR HOSE for surface wear, cracking, bulging, or coupling leakage. Replace immediately if pressure loss, hose deformation, or airflow restriction is detected.

Also indicated as 55019904, 550-199-04, and AIR HOSE 55019904, this pneumatic hose is widely used in high-demand drilling systems requiring durable and vibration-resistant air delivery.
