The new standard in locking air chucks!

• Six steel jaws lock onto any Schrader valve to create a secure, hands-free connection.
• 1/4” NPT thread compatible with most standard air hoses
• Hardened steel collet fits all standard Schrader valves [VG8/8V1 valve threads]
• Rated to 150 PSI - suitable for garage and industrial airline systems, auto and manual tire inflators, portable pressure gauges, and constant pressure systems
• Heavy-duty construction built to last and stand up to everyday use in even the busiest tire shops, service bays, and garages.
• AVAILABLE IN 2 STYLES: Open Flow or Closed Flow
• OPEN FLOW: Air passes through freely on or off the valve stem. For use with inflator gauges and automatic systems. If you are controlling your compressor's airflow through a trigger or foot pedal, then you want an OPEN flow.
• CLOSED FLOW: Chuck must engage the tire valve for air to flow. For use directly from a tank compressor's air hose. If you are putting the air chuck directly on the compressor hose, you want a CLOSED flow, so that air stops flowing when you aren't attached to the valve stem.
• If used with a multi-hose inflation kit, use CLOSED FLOW LockNFlate Air Chucks.
• For use on Milwaukee®, DeWalt®, or other battery inflators, choose an OPEN FLOW LockNFlate® Air Chuck.
