1.2-in-1 car valve lever plug with universal 7.8 mm male thread. It features a locking air chuck that matches the thread of American and French standard tyre valves and is compatible with the internal thread of twist-on tyre valve connections. The quick coupling tyre nozzle is designed to prevent air leakage. The valve extension is 16 cm long and is soft yet tough. Materials and durability: the air chuck is made from brass and wear‑resistant plastic. Brass provides good corrosion resistance, and the thickened plastic handle can be quickly locked to prevent leakage during inflation. The construction offers a long service life for many uses. Precision and performance: compact design for fast, secure connection and disconnection to the tyre valve. It minimizes air loss during inflation and allows free airflow through the feed, even if the valve is not locked. This promotes more accurate tyre pressure control, contributing to a safer and more comfortable ride. Easy installation: connect the inflatable hose to the valve adapter, screw the other end to the tyre valve, and press the converter handle to open the air pump. Press the release valve on the car tyre air chuck to disengage when finished. Use scenarios: - Home garage or driveway maintenance of car tyres, enabling quick and reliable inflation. - Roadside emergencies or mobile service where a portable air pump is used with standard tyre valves. - Workshop or service setting for repeat inflations on tyres with twist-on valve connections.
