Features: The dual chuck air tire head has a protective chrome-plated metal body and the head is made of tough, impact-resistant ABS material.

Both lock-on air chuck and dual head tire chuck feature a 1/4 inch NPT female thread for easy connection to air fittings or tire inflator gauges for tire inflation.
