However, the sellers are amazing and incredibly helpful. I strongly recommend buying from them, as I will be in the future. ### ⭐ Parts do not fit, yet search filter confirmed the fitment. *by D***F on April 19, 2026* Warning, before purchasing this kit make sure to verify the thread size used in your vehicle. I filtered the search results by make / model / year and confirmed the fit, yet the high side adapter does not fit. The high side adapter female thread is 7/16"-20 the fitting on my high-pressure liquid line is 3/8"-24. Now my car has no A/C until I can track down the correct adapter. The search filter is not accurate, at least not in my case. ## Frequently Bought Together - R12 to R134A Adapter, R12 R22 to R134A High/Low Fitting Port Retrofit 1/4’’ to 7/16"-20 UNF Conversion Adapter, Fits for AC Air Conditioner Refrigerant - Four Seasons (12721) R12 Service Valve Compressor A/C Fitting - Four Seasons 12722 R12 Service Valve Compressor Air Conditioning Fitting --- ## 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/153532540-aupoko-r12-to-r134a-ac-retrofit-fitting-adapter-kit-ac](https://www.desertcart.hr/products/153532540-aupoko-r12-to-r134a-ac-retrofit-fitting-adapter-kit-ac) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-16*
