Metal threaded inflator tube and extension hose designed for reliable tire inflation. Key benefits Threaded metal inflator tube (thread specification): durable and long-lasting, reducing the need for frequent replacement. Extension tube made of wear- and deformation-resistant materials; hose is not easy to break for dependable service life. Pneumatic chuck for tire inflation: compatible with car, bicycle, and motorcycle tires. Quick-connect extension tube securely connects and disconnects the tire nozzle, minimizing air loss during connection and disconnection. Function and performance Provides fast, secure engagement with tire valves via the pneumatic chuck for efficient inflation. Robust construction maintains shape and performance under regular use and resists common wear and tear. Designed to prevent air leakage when attaching or removing the nozzle, preserving correct tire pressure. Compatibility and use Intended for tire inflation of cars, bicycles, and motorcycles. Threaded metal inflator tube fits the product’s thread specification; the extension hose connects quickly to standard tire nozzles via the pneumatic chuck. Practical use scenarios Roadside bicycle repair: quickly attach the pneumatic chuck and inflate a flat tube with minimal air loss. Home garage car maintenance: use the durable metal threaded tube and extension hose for routine tire pressure checks and inflation. Motorcycle service: reliable, deformation-resistant hose provides consistent airflow during tire inflation and maintenance. Materials and care Metal threaded tube for durability; extension hose constructed from materials resistant to wear and deformation. Inspect connections and hose condition regularly; replace if damaged to maintain reliable performance.
