After years of having the very finest tire inflating guns, we've redesigned it to be even better. Our Digital Tire Inflating Gun is now easier to read and filling tires is now a simple one handed operation! Simply clip the locking air chuck onto the tire's valve stem and use the in line trigger to inflate to the correct pressure or bleed off air if you have too much. There's a backlight for night time use or in dark settings. The quick-flip lever locks onto standard valve stems. The large 1 1/2" wide and a 1/2" tall digital readout shows proper inflation in PSI, BAR, KPA or CM2 in .5 increments. It's surrounded by a rubber hood to guard against accidental whacks! The long 14 1/2" rubber hose has internal braiding to stand up to years of abuse. Comfortable non-slip grip that's easy to clean. Has a 1/4" NPT thread on the bottom to install your own quick disconnect fitting or hose. Auto off feature turns the gun off after 1 minute of non use. This Tire Inflating Gun is so nice I can see some of you opening up your own inflating stations! Needs an air supply to operate, but you already knew that.
