Yes it uses 1234yf I have no problems charging it with regular 1234yf refrigerant. I saw all the reviews of others having issues with the badly cheap connector. I was just thinking they bought for the wrong refrigerant type and surely I wouldn't have NO issues. I was wrong. When I attempted to squeeze air out of tube. I thought it was broken nothing coming out. Well Like Other reviews You have to press extremely hard thought I was going to break it. Next I attempted to connect to low port. Mine is way at the bottom of vehicle so have to stand on chair hard to get at especially with this very short tube. The thing would not click on to the port. it would go on but just sit very loosely after about 10 minutes thinking this should click on there no problems like all the other refrigerants i have use. I thought will maybe it's just supposed to fit on this way. So very hesitant I thought lets try it. turn the vehicle made sure compressor is turning and begin to press the button Very hard cause only way it will come out and wouldn't you know the fluid leaked all out the sides of port so after being very disappointed. I tried some more to get that thing on the port NO Go and cause this fluid was leaking out sides of port I made even more of mess So now I wouldn't be able to tell if I got a leak somewhere. I'm out 30 dollars now cause apparently there is no return on this item!! I feel like I've been scammed! The only good thing about this stuff it glows very nicely under the UV light and makes a big mess cause of crappy cheap plastic connector. ## Frequently Bought Together - TSI Supercool 39241B-YF Total Leak Stop and U/V Dye, 1 oz (HFC Free BOV Can with 1234yf Adapter, Retail Box) - ZeroR® Genuine R1234YF in 8oz SSV Cans | 3 Cans with Zeror Service Label --- ## 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.tn/products/311554904-tsi-supercool-39241b-yf-total-leak-stop-and-u-v](https://www.desertcart.tn/products/311554904-tsi-supercool-39241b-yf-total-leak-stop-and-u-v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-25*
