InterDynamics 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,1 High Side Port and Retrofit Label

These parts almost did the job in retrofitting my AC system to R134a but the fault was my 1990 Miata and not the part. Check the clearance on the low pressure fitting + adapter as I couldn't attach the freon hose because the engine was obstructing access. I had to remove the R12 fitting and replace with an R134a fitting (couldn't use this adapter on the low pressure side)--again, because of lack of clearance which happens in small cars. The high pressure adapter screws over the R12 fitting so no access limitations created.

The adapters are well made and work. One important note: There is no mention of the fact that the low pressure adapter has a schrader valve installed in it. This requires that the adapter be longer than otherwise necessary, which is fine except in my case (90 Cadillac) there was inadequate space to connect the quick coupler of my recharging kit. I went to the manufacturer, idqusa.com, and they provided me with a discontinued shorter version, (no schrader valve) which worked perfectly. idq provided great service!

Doesn't have a valve core on the high side fitting, so I can't hook up a gauge for a reading the high side pressure.

"Interdynamics ACPRO Air Conditioning Conversion Adapter Kit with 2 Adapters includes 2 adapters covering all vehicles 1976 – 1995, excluding some GM cars 91 and up"and apparently Toyota. low side works, but i already had one of those. high side is way too large to fit.

i put the low side port on & by the next day all the freon i put in was gone. there was no seal in the bottom of the port. i did not know this .I had it on super tight also. last time i buy this brand, since i have to redo everything !!!!!

This was exactly what I needed to convert my 84 Mazda rx7 to r134a to get the ac working again

Item was exactly as described It was packaged securely for shipment and it was shipped fast and efficiently. Met my expectations and was just what I needed to upgrade my old R12 AC system to R134A. Can't say much more than that really.

High side did not fit my 1987 Cressida. Low side was fine. Went to Walmart and purchase the adapter kit (another interdynamics, not sure what kit number) from there and it worked fine.

Product worked as described on my 86 chev

Arrived as advertised.
