The Staun Tyre Deflators are four automatic deflators made entirely of brass. Set them once to the pressure you want, screw one onto each tyre valve, and they let the air out and stop by themselves, so all four tyres end up at the same pressure. They adjust from 6 to 30 PSI, weighed 147 g with their leather pouch, and cost me $80.
What’s in the box
Four solid brass deflators, preset to 18 PSI from the factory, in a leather pouch with press studs. They can be fully unscrewed, which makes it easy to clean out any sand that gets in.

Setting them
This is the fiddly part, and the reason the Staun scores lower than newer sets for ease of use. There’s no scale to dial in: you let a tyre down to your target with a separate pressure gauge, screw a deflator on and adjust it until it stops at that pressure, then lock it and set the other three to match. Our guide to setting Staun deflators goes through it step by step. Once they’re set, they stay set.
On the tyres
Screw all four on and walk away: each deflator lets air out until its tyre reaches the set pressure, then shuts off. The result is the real strength of the Staun: all four tyres end up at the same pressure, far more even than doing it by hand. Below 12 PSI you lift the pin inside by hand to start it, a small extra step for very low pressures.
Build and carry
Brass doesn’t rust, so they handle beach driving and muddy tracks, and the knurled bodies grip well with dusty fingers. The leather pouch protects them and keeps them together, and at 147 g the set lives in the glovebox. After a sandy day, unscrew them and rinse out the grit.
Deflators compared
We also use the KickAss Tyre Deflator Set and the CampBoss Boss Air set. Both are easier to set than the Staun. The KickAss cost less but only goes down to 10 PSI; the CampBoss goes down to 5 PSI and is our top-rated set. Our tyre deflators guide compares all the deflators and gauges we’ve tested.

Conclusion: Staun Tyre DeflatorsConclusion
The Staun Tyre Deflators are tough, all-brass automatic deflators that leave all four tyres at the same pressure, adjustable from 6 to 30 PSI and 147 g in a leather pouch. Setting them takes a separate gauge and some patience, and below 12 PSI you start them by hand. I paid $80; once they’re set, they’re a set you’ll keep for years.

Yes, if you don't mind the first setting. I paid $80 for a set of brass deflators that will last for years. Newer sets with a scale are easier to set.
