R12 to R134A Car AC Retrofit Fitting Adapter Kit, R12 R22 to R134A High/Low Air Conditioner Fitting Port, 1/4" to 7/16"-20 UNF Automotive AC Conversion, Universal for VehiclesFREE AND FAST SHIPPING!
- Secure Connection: Our car AC retrofit fitting adapter kit core function is to adapt legacy R12/R22 systems for R134a refrigerant compatibility, resolving incompatibility issues. The precision threaded design ensures a tight, stable valve connection that maintains proper system pressure.
- Color Coded Identification: Our car AC retrofit fitting adapter kit uses red and blue protective caps to distinguish high-pressure (HP) and low-pressure (LP) sides. Red indicates high pressure (marked "H"), while blue denotes low pressure (marked "L"). This allows users to quickly identify connections and avoid misalignment. Additionally, the protective caps cover the fittings when not in use, preventing dust from entering internal components.
- High Quality Material: Our car AC retrofit fitting adapter kit is crafted from high-quality nickel-plated copper. Copper offers good thermal conductivity and structural stability, ensuring a tight fit with air conditioning system ports and guaranteeing smooth refrigerant flow during charging. The nickel plating forms a dense protective layer that significantly enhances wear resistance, minimizes friction during installation, and extends service life.
- Wide Application: The low-side (blue) connector in our automotive AC conversion kit measures 1/4" (7/16"- 20) x 13 mm, while the high-side (red) connector measures 1/4" (7/16"- 20) x 16 mm. This product is compatible with older R12 and R22 air conditioning systems featuring 1/4-inch SAE or 7/16"-20 UNF connections, converting their charging ports to accommodate R134a quick-disconnect hoses.
- Easy Installation: First, turn off the car's AC and relieve system pressure. Remove the conversion kit, then take off the plastic protective cap to expose the threaded fitting and removable valve. Align the valve with the AC port and screw the threaded end of the kit onto it until it's securely tightened and won't budge. Gently pull on the kit to confirm the connection is stable. Finally, check for any issues, and installation is complete.
