Milton is well known for inflator gauges. This large bore dual head chuck inflator gauge is perfect for off road equipment such as bulldozers and dump trucks. The heavy duty construction provides a long service, even with daily use. This inflator gauge comes with a 15" hose and offers a pressure range of 10 to 160 PSI in 2 pound increments. The dual heads are ideal for inner duals and even offer 3/8-24 lock on threads, so there is no need to hold the chuck head on the tire valve. Gauge is complete with magnifying viewing window for a full view of scale. 1/4" NPT air inlet.
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 tires 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 its 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.
