Fill all your tires to the recommended pressure with the STEELMAN 99062 0-150 PSI Digital Gauge Inflator with 15-Foot Whip Hose. Using its standard 1/4-inch NPT female inlet this tool can be easily attached to most existing air compressor lines. The easy-to-read backlit LCD screen can be set to display pressure in one of four different scales - psi, Bar, kPa, or kg(f)/cm2 with a simple button press to switch between them. To prevent premature draining of the included 9V battery, the gauge has a built-in automatic shut off feature that is set at 3 minutes but can be adjusted in 3 minute intervals up to a maximum of 21 minutes. The 15-foot whip hose with attached clip-on chuck makes it easy to reach recessed valve stems and to allow you to keep a safe distance when inflating high pressure tires. To help protect the electronic gauge in the event of an accidental drop a high-impact ABS plastic boot surrounds the gauge. Stop filling your tires on your car, truck, ATV, motorcycle, or bike until it just looks like they're good to go, know for sure with the STEELMAN digital gauge inflator and get the best and longest use from your tire investment.
