ALL-TOP Adjustable Auto-Stop Tire Deflator Valve Kit (8pcs, with 5 Valve caps)

Amazing product, very accurate when you take your time setting them up precisely.

What an amazing addition to my off-road gear. Exactly as described and when set properly they are accurate within 1 psi. Easy and convenient to operate. I’ve had expensive deflators and these are comparable. Would purchase again.

The design makes them very easy to set, the only issue I have found is that it is hard to get them to all match up the first few trys. They are light weight, no leakage, they seem very durable, the speed in deflating my 37s very quick. The appear to be a good value for the money so far.

Sa fait exactement ce que c’est supposé faire et ça fonctionne très bien merci!

These are a great product! I have another set that looks identical to the Stauns, and these All-Top deflators work much better. These are consistent, but that depends on user care in consistently setting the desired pressure. These start very smoothly and shut off nicely. The lesser performing deflators had a simple flat-head valve seat, but the All-Tops use a chamfered valve seat, and I believe that is why they perform so smoothly and consistently. For my test, I set the deflation to a bit less than 20psi on the front tires and a bit less than 30psi for the rears. The fronts (both) automatically deflated to 18.5psi, and both rears went to 28.5psi. The reason for being less than the marked 20 and 30psi was that I set them just below the lines instead of exactly on the lines. The differences were trivial in terms of driving performance. One thing to be aware of is that after use, the adjustment should be backed out as much as possible without disassembling the units in order to relieve the spring compression and extend the product life.
