Review on 🚗 AutoEC Adjustable Brass Tire Deflator Kit for Off Road Vehicles - Ideal for Car, Truck, Jeep, and ATV (Pack of 4) by Rick Pickering

I received them quickly, I bought them when airing on the beach. I immediately opened them up to check the seals and debris and they were fine, the spring is not brass. I adjusted them all to around 15lbs and then tested them - no issues with testing so far. Vents from 35psi in about two minutes, no loud whistle, I plan to take them out in about 10 minutes. I see no point in leaving them there if there is no air.
