Like no other air chuck on the market, the LockNFlate's six steel jaws lock onto any Schrader valve to create a secure, hands-free connection. The heavy-duty construction is built to last and stand up to everyday use in even the busiest tire shops, service bays, and garages.
Features:
OPEN FLOW: Air passes through freely on or off the valve stem. For use with inflator gauges and automatic systems.
CLOSED FLOW: Must engage the tire valve for air to flow. For use directly from a compressor or air hose.
