Straight Lock-On Air Chuck - Open-Flow

The Difference between Open & Closed Air Flow Chucks: Open-Type Air Flow Chucks: The Open-Air chucks employ a check valve which will not seal the opening of the chuck when pressurized. however it will open the core on the tire valve creating an open passage between the chuck and tire. Therefore an OPEN check air chuck should be used on an air-line gauge in order to function properly. Closed-Type Air Flow Chucks: Closed Type Air Chucks employ a check valve which seals the chuck closing the air passage while it is not being used and when used it will open the core on the tire valve allowing the pressure from the hose to be transferred to the tire. When a live air-line is used for non-gauged inflation of the tire a CLOSED air chuck should be used.
