Review: Rubber washer seals squish and block air flow (Fixed) - 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. Review: Chuck some Air in it - Phenomenal build quality. I bought these to replace the locking air chuck that broke on my digital inflator. Upon receipt and comparison, I could instantly tell these are beefier. The corners are a bit sharp and a little rounding wouldn't hurt but I'll take a high quality and affordable tool over a pretty one any day. And after two years, I'm still on the first one without any issues. One other downside of it being bigger is sometimes I have to wiggle it a bit to get it past some hubcaps, but they're few and far between. Definitely recommend grabbing a pair of these to upgrade or repair your tire inflation setup. ## Features - 250 PSI RATED BRASS COMPONENTS are designed for heavy-duty use with tire inflators and gauges - COMPATIBLE WITH SCHRADER valves; the closed flow design allows air to flow when the internal flow valve is open - ¼" FEMALE NPT THREADS fit most air inflators - HEAVY DUTY STRAIGHT TIP makes filling tire hassle-free; the locking clip keeps the chuck attached to the valve stem during inflation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078WVQL31 | | Best Sellers Rank | #8,108 in Automotive ( See Top 100 in Automotive ) #13 in Tire Chucks | | Brand | AstroAI | | Brand Name | AstroAI | | Capacity | 0.25 Inches | | Compatible Devices | Tire Inflator | | Customer Reviews | 4.5 out of 5 stars 6,621 Reviews | | Global Trade Identification Number | 00767452943575 | | Handle Type | hand-tightened | | Included Components | 2 tire chucks | | Item Type Name | AstroAI Air Chuck, Heavy Duty Closed Flow Lock On Tire Chuck with Clip for Inflator Gauge Compressor Accessories, Yellow | | Lock Type | Manual | | Manufacturer | AstroAI | | Manufacturer Part Number | 767452943575 | | Manufacturer Warranty Description | 1 Year Warranty | | Material | Brass | | Material Type | Brass | | Model Number | 767452943575 | | Thread Size | ¼-18 NPT | | UPC | 767452943575 | ## Product Details - **Brand:** AstroAI - **Capacity:** 0.25 Inches - **Compatible Devices:** Tire Inflator - **Material:** Brass - **Thread Size:** ¼-18 NPT ## Images ![AstroAI 2 Pack Air Chuck, Heavy Duty Closed Flow Lock On Tire Chuck with Clip for Inflator Gauge Compressor Accessories, Yellow - Image 1](https://m.media-amazon.com/images/I/719qxrQm+9L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: What is the difference, open flow and closed flow?** A: Lot's of info here that may confuse most. Open flow for hand held tire inflators or small 12v pumps. Allows the air to flow both directions, aka if your inflator has a pressure gauge and manual valve to let the air out of the hose. Closed flow is for direct connect to a compressor where you want the air to stop when you disconnect it, as in a shop or gas station. Both open the valve step to allow the air to flow. **Q: will this work on presta valves?** A: no from what i read you would need an adepter **Q: Im filling air tanks. Will i have to hold lever down or will it lock in open position?** A: If you are filling via a Schrader valve you will have to lock it on the valve otherwise it will not fit on the valve. Once on the valve you do not have to hold it down.. It least that has been my experience. I have been pleased with how these work. I bought mine to use on a Jaco inflator tool after the Jaco chuck failed. Not sure how it would hold up under commercial use. I use mine around the shop maintaining lawn equipment and personal vehicle tires for the last year **Q: I am making a harness to deflate/inflate all 4 tires simultaneously. When I connect the first one to a valve stem, are the other 3 closed, or leak?** A: They should only flow (to deflate/inflate) when they are engaged to a valve. If you scroll down on the photos, they actually have one that describes open vs closed. My first purchase I didn't pay enough attention and order "open" ones and they leaked thru. Then I ordered the closed ones and they have worked great since. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Rubber washer seals squish and block air flow (Fixed) *by R***L on October 15, 2018* Review Update: 2/27/19 AstroAI has contacted me and sent me a replacement set of Air Chucks.
