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 ### ⭐ Review *by S***D on 8 April 2025* Item returned due to incompatibility ### ⭐⭐⭐⭐ Review *by A***Y on 17 December 2021* La pieza funcional, necesitaba factura y solo me mandaron nota .

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!!! ## Frequently Bought Together - AstroAI 2 Pack Air Chuck, Heavy Duty Closed Flow Lock On Tire Chuck with Clip for Inflator Gauge Compressor Accessories, Yellow - LUMITECO 2-Pack 1/4 Inch Female NPT Closed Ball Tire Inflator with Clip, Locking Quick Connect, Clip-On Air Chucks for Truck RV Auto Car Air Compressor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/174609493-air-chuck-heavy-duty-closed-flow-lock-on-tire-chuck](https://www.desertcart.hr/products/174609493-air-chuck-heavy-duty-closed-flow-lock-on-tire-chuck) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
