Includes dust cap and retrofit label. Certified A/C Pro Automotive Air Conditioning R-12 to R-134a Retrofit Valve Adapter is a professional grade retrofit valve kit that works with R-134a refill fittings. Fits all vehicles pre-1994. Review: Works as described. But if you are retrofitting your car from R12 to 134a, you might want to consider getting a full retrofitting kit. You get 3 cans of 134a, both low and high side adapters, and the hose/gauge to run the can into your car. The full set I got was only about double the cost of this one fitting. I bought this fitting to work with the pierce valve I got to allow us to charge our freezer that uses 134a, but had no fill port on the line. Now I can charge it using automotive style 134a refill cans.

I wish I could've found one of these in a real physical store, but Amazon saved the day after I had gone to Autozone and Home Depot... This works excellent if you're trying to refill an R12 system with R134a, works flawlessly and doesn't leak. --- ## 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/257359373-interdynamics-certified-ac-pro-car-air-conditioner-adapter-valve-converts](https://www.desertcart.hr/products/257359373-interdynamics-certified-ac-pro-car-air-conditioner-adapter-valve-converts) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-30*
