With the LockNFlate® Air Chuck, achieving the perfect tire pressure has never been easier. Its unique locking mechanism securely attaches to the valve stem, eliminating air leaks and ensuring a tight seal every time. Six steel jaws to lock onto any Schrader valve to create a secure, hands-free connection.

• Durable, spring-loaded TPU seal
• Fits all standard Schrader valves (VG8/8V1 valve threads)
• Heavy-duty construction for strength
• Suitable for use on: Garage and industrial air line systems; Auto and manual tire inflators; Portable pressure gauges; Constant pressure systems

• 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.
