## Description

Certified A/C Pro Automotive Air Conditioning R-12 to R-134a Retrofit Valve Adapter for 7/16 inch low side port is for converting automotive air conditioning systems from R-12 to R-134A. 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.
Review: Cheap price

Perfect for what I needed. 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.
