Instructions said to use this and then gas up the AC, but I had gassed up my AC first (2 weeks earlier) then ordered and used this; still worked great! 3 months later and my AC is still cool! ## 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.com.kw/products/311554904-tsi-supercool-39241b-yf-total-leak-stop-and-u-v](https://www.desertcart.com.kw/products/311554904-tsi-supercool-39241b-yf-total-leak-stop-and-u-v) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
