#2 TOP OFF KIT - This kit contains a 12" R1234YF HD Brass Can Tap with Gauge & 2 cans of R1234YF. 2 cans should fill the majority of empty systems. 1 can is only enough to fill a slightly low system and 3+ cans would be better for large systems and to have extra on hand.

GENUINE R1234YF – This product is genuine and is purchased directly from the manufacturer in the USA. This product should only be used in R1234YF system. Please check the service sticker on your system and/or vehicle to identify the system type.

8OZ CANS – Cans are 8oz net weight. Gas is measured in weight when compressed. Please don’t shake the can and think “this doesn’t feel full”. It is, we promise. Different gases have different weights when compressed. R134a is 12oz in this can, ZeroR AC Refrigerant is 6oz in this can, all are 100% full.

UNIVERSAL - ZeroR AC Refrigerant is a hydrocarbon that safely bonds with chemicals like R134a, R1234YF and R12. We can only advertise this product to be used in R134a systems due to EPA regulations in the USA on both R12 and R1234YF systems. EPA also prohibits mixing refrigerant types. See the description for all legal disclaimers.

EASY INSTALL - This product installs just as easily as any R134a products. Cans even have R134a threads and the majority of R134a can taps will work for these cans.

6oz CANS - Refrigerants are compressed gasses and are measured by weight, not by liquid volume such as water. All gasses compress differently and produce a different weight. ZeroR AC Refrigerant is low weight compared to R134a, but its performance is equal to 16oz of R134a.

PERFORMANCE BOOSTER KIT - ZeroR Permafrost is a performance booster to all R1234YF AC systems. PermafrostYou can use as many cans in your system as you wish, while being sure not to overfill the system with the included can tap with gauge. No additional tools required.

KIT CONTENTS - 3 Cans of ZeroR Permafrost are 4oz by weight. The contents are a blend of the proprietary performance enhancer as well as a refrigerant to propel the additive into the system. The can tap is 12” in length with a gauge metered for R1234YF systems. Standard R1234YF can taps will not work on ZeroR branded R1234YF cans, because our cans have a unique thread.

10 MINUTE INSTALL - Please read the can label for important details. (1) Turn your vehicle on, set the AC to max cool & max fan. (2) Connect the can tap to the first can and the other end to the low side service port on the vehicle. (3) Flip the can upside down Use the valve to release the refrigerant into the system. Every 10-15 seconds close the valve to view the pressure gauge. Repeat step 3 until the pressure gauge indicates the system is full. Do not overfill your system!
