Features: The connection is firm and the tire can be inflated quickly. When the internal flow valves are open, the normally open design allows air to flow. The upgraded heavy-duty brass gas chuck makes it easier to lock the valve stem and prevent air leakage. Locking clip: When using the air chuck to inflate the tire or measure the pressure, use the locking clip to secure the chuck on the valve stem for sealing. Fit type: 12.5-13mm diameter threaded NPT, compatible with most tire inflators, wheel pressure gauges, and compressors. The straight chuck is suitable for all vehicles. Durable and resistant to damage. Specifications: Material: Copper Size: Approx. 7 x 7 x 2 cm / 2.76 x 2.76 x 0.79 inches Package includes: 1 x Tire Inflator Chuck Note: 1.
