• Authentic HFO-R1234YF - This product should only be used in R1234YF systems. Please check the service sticker on your system or vehicle to identify the system type. This kit also includes a ZeroR service label for easy identification of the servce date and working pressures.
• 8 oz Cans – Cans are 8 oz net weight. Gas is measured in weight when compressed. Please don’t shake the can and think that it doesn’t feel full. Rest assured that it is. Different gases have different weights when compressed.
• Reverse Threads - These R1234YF cans are different from the older, more traditional, cans of refrigerant such as R134a. They have left hand, or reverse threads. This means you will need to turn the can counter clockwise to insert into your charging hose can tap.
