Set your target PSI on the deflator, then screw it onto each tyre's valve stem. Each deflator releases air automatically and stops on its own at exactly the pressure you set, so all four tyres end up at the same PSI without you having to recheck them with a gauge.
They cover different PSI ranges for different vehicles and terrain. Standard Range and Quickset are adjustable 6-30 PSI (Quickset adds a built-in precision gauge on each deflator). High Range covers 15-55 PSI for heavier vehicles running higher pressures. Low Range covers 1-10 PSI for rock crawlers running beadlock wheels at very low pressure.
Grip the knurled brass body and turn the adjustment cap to your target PSI, then screw the deflator onto the valve stem by the cap only. Turning the wrong part during handling is the most common way a setting gets bumped.
Every set is precision made and individually quality-control checked by a technician at the Staun facility in Queensland, Australia — the same standard since 1998.
Staun deflators thread onto standard tyre valve stems, the same type found on cars, trucks, SUVs, and most trailers. Choose the PSI range that matches the pressures you actually run — see the range comparison above.
Staun Tyre Deflators are sold on Amazon. Each product page on this site links to its Amazon listing.
