- Hardened steel collet fits all large bore Schrader valves [VG12/12V1 valve threads]
- 250 PSI high-flow design - making it faster and easier to fill large tires
- Heavy-duty construction that is built to last
- 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
- U.S. PATENT #11913582
