Milton® is well known for inflator gauges. This dual head straight chuck inflator gauge is made with heavy duty construction, providing for long life even under extreme use and conditions. Perfect for high pressure applications, this inflator gauge offers a pressure range of 10-160 PSI. The dual heads allow for easy access into inner duals. Equipped with a magnified viewing window, this tire inflator gauge has a full swivel chuck and deflator valve. Gauge and valve cartridges are both replaceable. 1/4" NPT air inlet. Meets OSHA regulation 1910.177.

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.
