AstroAI 2 Pack Air Chuck, Heavy Duty Closed Flow Lock On Tire Chuck with Clip for Inflator Gauge Compressor Accessories, Yellow

Review Update: 2/27/19 AstroAI has contacted me and sent me a replacement set of Air Chucks. When I received the replacements, I had my doubts that I may have the same experience since everything looked identical. Much to my pleasant surprise, the new chucks I received which still used the 1/4" thickness rubber washer seals which I suspected to be the problem, did not cause the same problem. I'm uncertain if AstroAI made some type of improvement to the rubber washers, or if there was something defective about the original washers with the chucks I received. Maybe they use a stiffer rubber for the washers now? I can't say for certain since the original washers were definitely causing me problems. I've attached an image of the replacement chucks with the rubber washers I received to better show how I've installed these onto my air compressor. Whatever the problem was, this chuck now seems to be working correctly with the supplied rubber washer seals where I am going to revise my review from 1 to 5 stars. Thank you AstroAI for the great customer service and taking care of the problem I originally experienced. The only con at this point I'm currently seeing which is not due to the chuck's design but more to my specific application. I have an onboard air system on my Jeep Wrangler where I have the air hoses mounted under my Jeep for added convenience of airing up and down my tires for off road use. These chucks therefore get exposed to the elements being mounted under my Jeep and is the reason the original set I had, rusted and needed to be replaced. Brass doesn't rust but the metal parts such as the spring and push lever do. I really wish there was a vendor who made these chucks who either painted the steal pieces or made the complete assembly out of brass to prevent the chucks from rusting. To overcome this, I painted and greased the pieces which are not made of brass to help combat my rust concerns for my application but that's kind of a PIA. It would be nice if a manufacturer made air hose chucks which resisted corrosion. Original review below in it's entirety. ----------------------------------------------------------------- I purchased these to replace a similar set of open flow clip on tire chucks which had rusted. While the overall construction of these chucks seem good there is one major flaw in their design. Inside the screw on side there is a rubber washer which is there to help seal the connection of the hose you are screwing these on. The rubber washer is 1/4in thick. When you screw these chucks onto the air hose, the rubber washer will compress but it compresses too much where the hole in the center of the washer will become blocked and thus not allow any air to flow through the chuck. When I initially installed one of them, I had thought that maybe these were closed flow chucks since my air compressor was getting back pressure when I turned it on and no air was coming out of the end of the chuck. I therefore removed the chuck and found it was indeed an open flow chuck. I then started to gradually fasten the chuck onto my air hose. At a finger tight state, air was flowing out of the chuck as it should but as I continued to tighten the nozzle down the air flow through the nozzle continued to get less where once it reached a tightness I felt was good to hold the chuck onto the hose, there was absolutely no air flowing out of the chuck. The only thing I could surmise was that the rubber washer was squishing down to create a proper seal like it should, but at the same time it was also closing off the inner hole of the washer that lets air flow through the chuck. I pulled the rubber washers out and tightened the chucks back onto the air hose and sure enough, the rubber washer seal was the problem. What I ended up doing was pulling out the rubber washer seals from the rusted chucks which I was replacing and noticed those washers were only 1/8in in thickness and I inserted those rubber washers into these chucks. They worked properly when I used them in these chucks, the chuck was held on tight and air was able to flow from the chuck. If you buy these chucks, you're going to either have to remove the rubber washer seals, file down their thickness to about 1/2 their size or replace the washers like I did, or only tighten them on the hose so they're finger tight. Otherwise you will risk restricting or blocking the air flow coming out of the chuck. I used both of the chucks and had the same problem on 2 different air compressors. Such a poor design due to the included rubber washer seals, to an otherwise decent quality open air flow chuck.

I purchased these for off-road use. I made a tire air-down/air-up manifold so that I can connect all four tires on my Jeep at once. These air chucks are great. I bought these to replace the first set of chucks that I discovered did not like dust and dirt. The chucks are more reliable and install easier on the tire with gloves on. I needed a hands-free connection that allows me to air up/down all four tires at once. These are great!!!

works great, even with older tire valves

It came early and works as described

It's well built and sturdy but I couldn't get it to securely fasten to the tire valve so air leaked out of the connection. I tried multiple times on multiple tires without success. Returned it and looking for an option that fastens more securely. Update: 4/7/2025. After my initial review of the product, AstroAI Customer Support proactively reached out to me to discuss the issue I had. After sharing additional details on what wasn't working, they offered to send me a replacement in an attempt to resolve the my issue. I agreed and the replacement air chuck worked perfectly. No product is ever 100% defect free and that isn't my expectation but customer service is what makes or breaks a business and in this case, the customer service was top notch. I appreciated that they look at the reviews and work to resolve any open issues.

I should have bought these years ago. I bought them for all of my air guns. They go on easy and work great.

I bought this to build a DYI CO2 chamber. It works great and very pleased with it. It is still going strong after 5 years. Please note, if your building a CO2 chamber to always inspect all parts for leaks before and after use. Perfect size I needed, great value for money, ease to use and perfect air flow.

The chuck doesn't really stay locked. So I hardly ever use it and just keep pressure on the chuck against the tire stem while inflating. When I do try to lock it (i.e. by letting go of the chuck) I can hear air escaping and it stops leaking if I hold the chuck and apply pressure into the tire stem. It's not a big deal for me since I stay on top of things and top off the air in my car tires often but I can see this being pretty annoying if i had to fill a large truck tire that keeps going flat.
