Did work on my father's 1987 Lincoln Town car 5.0 liter. **Q: Will this work on a 1989 Volvo 244?** A: Only the low side. Your 240 likely has the “Kiki” compressor which its high side fitting interferes with the adapter in this kit. The one 7/16” high side adapter that happens to thread on the compressor fitting will not seat all the way down.Any R134a coupler’s pin wont contact the R12 schrader on the compressor fitting. **Q: Will this work on a 79 chevy big ten?** A: I don't know in specific, i Know that if your car use r-12 as refrigerant gas, this kit can be use the refill with a r134a harness after the convertion, so you must check the refrigerant stiker inside the hood or your owner manual, first ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product *by D***. on October 10, 2025* Works as promised. Easy to use. ### ⭐⭐⭐⭐⭐ Perfect fit *by P***Y on September 24, 2025* Works perfectly. Doesn’t leak and very easy to install. Would definitely order it again. ### ⭐⭐⭐⭐⭐ Worked for 1987 Nissan D21 *by D***G on July 27, 2025* Used this to retrofit some R134 fittings on an old 1987 Nissan D21 hardbody pickup. Had exactly the pieces I needed and a couple left over as well. I'm actually running R152a (Dust Off, Computer Duster, whatever you want to call it) in the truck now with Ester oil and it is working great thanks to these fittings letting me hook up modern 134 gauges to it and recharging the system. ## Frequently Bought Together - CERTIFIED A/C PRO Car Air Conditioner Adapter Kit, Complete AC Conversion Adapter Kit Converts R12 to R134-A Refrigerant, Includes 1 Low Side Port, 3 High Side Ports and Retrofit Label, InterDynamics - TSI Supercool A/C Comp Lube, UV Dye, 8 Oz, Flsh PNT 442 F, red/Yellow Tint (P46-8D) - R12 to R134A AC Retrofit Fitting Adapter Kit, R12 R22 to R134A High/Low Fitting Port Retrofit 1/4’’ to 7/16"-20 UNF Conversion Adapter,Fits for AC Air Conditioner Refrigerant --- ## 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.be/products/1708181-car-air-conditioner-adapter-kit-complete-ac-conversion-adapter-kit](https://www.desertcart.be/products/1708181-car-air-conditioner-adapter-kit-complete-ac-conversion-adapter-kit) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-09*
