ARB E-Z Deflator with Digital Gauge (ARB510)
ARB E-Z Deflator with Digital Gauge (ARB510)
The ARB E-Z Deflator (ARB510) is a tire deflator and pressure gauge in one tool. Unscrew the brass chuck onto a Schrader valve, pull the lever to lift the valve core out of the way, and air dumps fast. Thread the core back down and the backlit LCD shows you exactly where you landed. No second gauge, no guessing.
The gauge reads 0-200 psi and is accurate to +/- 1 psi across the 15-75 psi band most rigs air down to. It shows four units — psi, bar, kPa, and KgF — so it works no matter how you think about pressure. The 250mm braided hose has solid brass fittings and a rubber bump guard to take a drop, and the blue backlit display stays readable at dawn or after dark. Max supply pressure is 350 psi.
Power comes from 2x AAA batteries, good for up to about 200 hours of use. The unit ships in a carry pouch that fits a door pocket or a recovery bag. Built for airing down before sand, rock, snow, or washboard, then dialing pressure back up at the trailhead.

Overview
The ARB510 combines a rapid tire deflator and a digital pressure gauge in a single handheld tool. Pull the valve core to dump air fast, reseat it, and read exact pressure on the backlit screen.
Key features
- Removes the Schrader valve core for fast deflation, then reseats to read pressure
- Digital gauge: 0-200 psi, accurate to +/- 1 psi at 15-75 psi
- Reads four units: psi, bar, kPa, and KgF
- Blue backlit LCD for low-light readings
- 250mm braided hose with brass fittings and a rubber bump guard
- Runs on 2x AAA batteries, up to ~200 hours; max supply pressure 350 psi
Use cases
Built for airing down at the trailhead before sand, rock, snow, or washboard, and topping pressure back up afterward. One tool covers all four tires and replaces a separate deflator and gauge.

How does it deflate so fast?
The brass chuck lets you lift the Schrader valve core out of the airflow, so air dumps far quicker than pressing a pin. Reseat the core to stop and read pressure.
How accurate is the gauge?
It reads to +/- 1 psi across the 15-75 psi range, which covers the pressures most rigs air down to off-road.
What units does it display?
psi, bar, kPa, and KgF on the same screen.
Does it need batteries?
Yes, 2x AAA, good for up to about 200 hours. Carry spares on long trips since the readout is digital.
Will it fit my valves?
The screw-on chuck fits all standard Schrader valves found on most vehicle tires.
Can I air back up with it?
It reads pressure while you inflate from an external source up to a 350 psi supply, so you can check as you top off.
