1STKIT Quick Connect Automatic Tire Deflators - Blue, Set of 4 (6-44 PSI)
Air down all four tires at once and walk away: clip a 1STKIT deflator on each valve, and each one stops by itself at the pressure you set. 6-44 PSI in 0.5 PSI steps, blue anodized aluminum, packed in a protective tin.
Description
Lower pressure means more grip and a smoother ride on sand, snow, mud and rock. Getting there shouldn't mean kneeling at every wheel with a gauge. 1STKIT Quick Connect deflators do the work for you: set the pressure once, clip them on, and they shut off on their own.
HOW IT WORKS
- Set your target PSI on the dial (factory preset: 20 PSI).
- Remove the valve caps and clip a deflator onto each valve - no threading, no tools.
- All four tires deflate at the same time. Each deflator closes fully when its tire reaches the set pressure.
- Unclip, check with your gauge, and hit the trail.
In our real-tire test, a tire went from 40 to 20 PSI in about 140 seconds. Most off-road tires take 2-3 minutes, depending on tire size and starting pressure.
BUILT FOR THE TRAIL
- Quick-connect clip: snaps on and off the valve in a second, even with gloves on.
- Precise: adjustable from 6 to 44 PSI in 0.5 PSI steps. Use the auxiliary scale to match the deflators to your own gauge - after calibration they typically stop within about 1 PSI of your setting.
- Repeatable: in our test of 20 back-to-back deflations at 20 PSI, every result landed between 19.2 and 20.7 PSI.
- Tough: 6061 aluminum body with a corrosion-resistant blue anodized finish.
- Ready to go: the set of 4 lives in a protective tin that fits in a door pocket or glovebox.
Note: out of the box, the preset can read 0-3 PSI different from your gauge. Calibrate once with the auxiliary scale and you're set.

Built for consistency
Repeatability Test
Repeated deflations typically stay within ±1 PSI of the set pressure. The chart shows our test data: 20 consecutive deflations at 20 PSI, all between 19.2 and 20.7 PSI.
Accuracy & Calibration
On first use, the preset value may differ from your gauge reading by 0–3 PSI. The final reading depends on your gauge, your tire size and model, and your valve stem.
The built-in auxiliary scale lets you correct for this. For example, if you set it to 20 PSI and your gauge reads 23 PSI, set it to 17 PSI. After this calibration, accuracy is typically within ±1 PSI.
Closes fully
At your set pressure the valve shuts completely with a soft "pop" you can hear up close, so the tire stops losing air. Some deflators do not shut off fully and keep leaking. Some other deflators behave like the lower curve in the chart.
