Features: The air hose is made of stainless steel. High-quality reinforced nylon wound rubber hose is durable and not easily damaged. This inflatable nozzle is a universal model for beautiful mouths and is widely used for tire inflation of trucks, buses, electric vehicles, motorcycles, electric unicycles, balance cars, etc. Function: Since the valve mouth is too short when the tire is inflated, the connection of the inflator is inconvenient, and the extension tube is installed to extend the convenience of inflation. Easy to replace and install so compressed air can quickly enter the inner tube. Screw one end of the adapter to the original inflator hose, press to fix the head of the adapter to the tire valve, and then start the inflator for fast, leak-free inflation.
