Any type of gauge with a dial indicator tends to be a delicate device -especially one that reads tire pressure. Working in motorsports, I quickly learned to keep my gauge by my side and to never let anyone else touch it for fear that it may become “adjusted”. I wasn’t just being OCD either. Drop it once, and it can easily be off by as much as 10 psi. That’s why I was stoked when ARB sent me one of their brand new inflation cases.


This slick piece of kit is designed to keep a bevy of ARB’s pneumatic tools safely in place, but will gladly accept other brands. I packed away the budget of my favorite air tools into the six specialized pockets, and my spare valve stems and shrader valves into the small zippered internal pocket -perfect. This small pocket is also great for storing the items that come in ARB’s pump up kit (adapters for soccer balls [futbols], air mattresses, and a lock on tire chuck).
Unzip the main YKK zippers and the case folds flat for easy access to your tool loadout. Two mesh pockets retain a pair of matching air hoses while four adjacent pockets, with hook and loop flaps, keep gauges and deflators organized and readily available. Just below the mesh pockets is a small zippered pouch and a single slot for a pen gauge. Once loaded up, I found the case perfectly fit the small cubby under the rear passenger seats in my Crew Cab RAM 2500.
The simple exterior consists of abrasion resistant canvas with the company’s standard orange, topo-pattern livery and comes with a sturdy rubber handle. Two reflective bands wrap the exterior  just in case the bright color still eludes you at night. PVC piping spans the length of the outer seams providing a spot more abrasion protection and a finished appearance. The overall dimensions (16” x 9.5” x 5”) are perfect for storing the case in ARB’s proprietary Outback drawer systems.

*Sidebar. I have noticed a few recent online posts where people have performed a side-by-side comparison of their tire pressure gauges only to discover they vary greatly in pressure readings. There are two reasons for these discrepancies. One, manufacturer tolerances; few (if any) gauge manufacturers do any sort of bench testing with their products. Thus, there can be vast differences in accuracy from gauge to gauge. Two, the gauge you are handling could have been dropped by a factory worker, shipping company, or you at some point. So what am I getting at? Tire pressure gauges should be checked periodically for accuracy to prevent over or under pressurizing your vehicles tires. This is important for tire wear, performance, and safety factors. This can be difficult since nearly every gauge you reach for is likely off by 20% or more. TPMS equipment, although not perfect, is fairly accurate and can provide you with insight as to the degree in which your gauge is off the mark. You can use this information to mark the gauge with a sharpie indicating that it is reading +2 or -3 PSI so that you can better measure pressure. Tire pressures should be checked when the tires are cold, ie. before hitting the road, and not when they are hot (unless you are working on a track car, then you will need both hot and cold pressures). Of course, there are tire pressure gauges that can be calibrated, but this procedure should be performed by a tire supplier at a racetrack, or an air tank supplier with the proper equipment. This is the only way to ensure that your gauge is displaying accurately, that is, until someone drops it again. No matter how you do it, be certain to protect and care for your delicate dial gauge equipment -your tires will thank you.
