The car tire inflator adapter is made of high-quality zinc alloy and copper, offering good performance, stability, and durability. The 90-degree locking air chuck features an 8mm standard tire valve fine thread. It easily converts the inflator connection to a locked connection without needing to clamp onto the tire stem. Ensures that air pressure inside the tire will not leak during inflation, even if the tire valve is not fully opened or locked. The air chuck adapter includes a deflation valve with a maximum pressure rating of 200 PSI. The inflation clip locks the flow clip open for easier tire inflation. To deflate, simply press down on the protruding yellow section. The 8mm threaded end is ideal for hose repairs and compatible with 8mm bore hoses. Allows quick connection and disconnection of the tire valve, preventing air pressure leakage. Insert the locking air chuck into the hose and hook it onto the stem until secure, then release the clamp. The external thread of the locking tire chuck matches the standard American tire nozzle, making it suitable for inflating tires with standard valves.
