Dual Truck Tire Inflator Gauge

Dual truck tire Inflator gauge offers a pressure range of 10 to 160 PSI in 2 pound increments. This set includes two 7' hose assemblies, two shut-off valves and one 12" swivel extended reach dual head chuck. Inflator gauge includes viewing window.

INSTRUCTIONS FOR USE:

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.
