Q:I have a R12 system that has been converted to R134 and want to add R134 to it but to keep the stock look of the classic car the R12 ports were kept. Is this kit going to allow me to add R134 to the R12 ports (keep in mind the system contains R134 so I will not be cross mixing the refrigerants) Just adding more R134 to R134
A:I'm glad to assist, Don! If you are only adding a small amount of R-134a to the low side port, you would not necessarily need such and extensive adapter kit. Most commonly you can utilize retrofit ports, such as AutoCraft Low Pressure Port Retrofit Valve (Part No. AC994/VA-1L) which is a 7/16" fitting for all cars or you could get an assortment kit if you prefer (Factory Air Retrofit Assortment Part No. 59980).
