1/4″ NPT air inlet


If using a dual head type tire chuck with an inflator gauge and notice air is escaping through the off-side once connected to the tire’s Schrader valve, simply release the trigger and remove the inflator from the Schrader/tire valve. Point the straight side of the outlet up into the air (make sure it’s not pointed at someone). Squeeze trigger, allow air to flow (gravity will cause the sealing valve to drop), and place the chuck end onto the Schrader/tire valve while air is still flowing. Air will start to flow into the tire.

Dual head type tire chucks are unable to inflate a completely flat (zero air pressure) tire. Tire air pressure would normally cause the sealing valve to move and seal the unused side of the chuck. However, if a tire has 0 air pressure, the self-sealing valve has no pressure to react to.

DRIVE SAFELY: Maintaining proper tire pressures improves vehicle handling, reduces risk of tire failure, improves fuel economy, and increases the life of your tires.
