Adjustable Auto-Stop Tire Air Down Kit (10-30 PSI) Screw-on Tyre Deflator Tool for Offroad 4x4 Vehicle Accessories

Worked as promised! Was out in the sand dunes and needed to air down to drive my truck in soft sand. Put them to 20lbs and it stopped on its own. So helpful. Did two trucks in less than ten minutes.

I've been trying to decide on a good air down solution and decided to try these because I was also ordering a Samout compressor. What I like about these over the type that removes the valve stem core is that I can just screw them all on and not bend down the whole time I'm trying to air down. They seem to be stout and they are very easy to use. The only reason I said I like them "mostly" is because two of them easily adjusted to 21psi and turned off perfectly. One of them took quite a few tries and effort to get it to 21 and I finally just accepted 22psi. And the last one took me some time to realize that it was "closing" at about 21psi but it didn't close right so it was still slowly letting it air. It was coming out fast enough that I thought it was just still working but it was going on for awhile so I checked and the tire was at 15psi. After adjusting and testing it a few times I realized I was hearing it "pop closed" and the air flow was reducing, just not stopping. I checked the pressure when I heard that sound and it was about 23psi. I adjusted it again and got it close to 21psi when I hear the pop close sound, I just have to be sure I'm paying attention. Overall they are a really fast way to air down with minimal bending or kneeling required. And if you care, the Samout compressor is fantastic so far.

I combined this with my power tank and this is the best investment I have ever done. I go off road a lot and air down to 10 PSI on 37 inch tires x 17 inch rims. Took about 2-3 min. Loved the fact that they also give you valve stem caps!

La calidad del material es muy bueno,Hace su función de desinflar automáticamente pero no es preciso ni consistente.Coloque el marcador a 20PSI y paró en 10PSIPara lograr los 20PSI coloque el marcador en 30PSIPero no todos son precisos, hay que ir probando uno por uno para ver el rango de error que tienen.Ya cuando lo tienes todos listos funciona bien.

Works as it should but difficulties in adjusting tire deflation

The deflators work almost as intended. The package included a set of valve caps. The valve caps were junk. Made of aluminum and they “rusted” onto one of my valves and broke it trying to remove it. The deflators work ok

Easy to use. I think this item is better than most, sturdy and just feels like a quality made product. The thing i like best is the fact that there are numbers to show pressure to set to. We go to the beach a lot, and it sure helps my back not having to bend down to deflate the tires.

These make airing down much quicker and easier. They are sturdy and come with a storage pouch.
