ARB Small Dial Tire Gauge (PSI/Bar, ARB506)
ARB Small Dial Tire Gauge (PSI/Bar, ARB506)
The ARB506 is a small-dial mechanical tire gauge that reads 0-70 PSI with a matching bar scale. The movement is a brass bourdon tube with geared internals, so the needle holds true across temperature, humidity, and altitude swings that push cheap pencil and digital gauges off. The dial sits behind a protective rubber guard that takes the drops and rolls that come with a tool living in a door pocket.
The real work happens when you air down. A flexible hose ends in a dual-angle chuck that seats on straight and angled valve stems, and an integrated bleed button lets out air while the needle reads live. You hold the chuck on, thumb the button, watch the pressure fall to your trail number, and let go. No pulling the chuck to re-check, no overshooting and topping back up. The low end of the dial is geared for the single-digit pressures you run in sand, rock, and snow.
It carries ARB's 3-year warranty and runs $34.95.

Overview
The ARB506 is a compact mechanical tire gauge built for airing down and back up off-road. A brass bourdon-tube movement reads 0-70 PSI plus bar, and a built-in bleed button lets you set an exact trail pressure without removing the chuck.
Key features
- Brass bourdon-tube movement with geared internals; resists temperature, humidity, and altitude drift
- Dual scale: 0-70 PSI and 0-4.8 bar, with the low end geared for airing-down pressures
- Integrated bleed button reads live while it releases air
- Flexible hose with dual-angle chuck for straight and angled valve stems
- Protective rubber gauge guard
- 3-year ARB warranty
Use cases
Built for setting trail pressures when you air down for sand, rock, or snow, then checking them again at the trailhead. It also handles routine daily-driver pressure checks; small enough to live in a door pocket or glove box and pull out whenever a tire looks low.

What pressure range does it read?
It reads 0-70 PSI on the outer scale with a matching bar scale. The low end is geared for the single-digit pressures you set when you air down for sand or rock.
Can I use it to let air out, or only to read pressure?
Both. The integrated bleed button releases air while the dial reads live, so you drop to your trail pressure and confirm it without pulling the chuck off the stem.
Will the chuck fit my valve stems?
The flexible hose ends in a dual-angle chuck that reaches straight and angled stems on most rims, including dual-wheel setups.
Does altitude or cold throw off the reading?
The brass bourdon-tube movement is built so temperature, humidity, and altitude don't shift the reading the way they can on cheap digital or pencil gauges.
Will it hold up living in the truck?
The rubber gauge guard takes the drops and knocks, and the brass movement is the part that resists drift over time. It's made to ride in a door pocket, not a padded case.
Is it covered if it fails?
Yes. It carries ARB's 3-year warranty.
