ZeroR® Permafrost for R1234YF AC Systems | Performance Booster | 3 Cans + 24" HD Can Tap Gauge
- PERFORMANCE BOOSTER CHARGE KIT - ZeroR is a performance booster for use with R1234YF AC systems. You 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.
- KIT CONTENTS - The can tap is 24 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. 3 cans of ZeroR Permafrost in 4oz cans.
- NOT A Full Refrigerant - This product is a support fluid performance booster. It is a combination of two ZeroR products in one. The first part removes moisture (moisture can cause damage and reduced performance in the system), and the second part reduces friction (friction can reduce refrigerant flow and cause compressor damage)
- 24 in Charging Hose with Can Tap & Gauge - New longer 24 inch connection hose accomodates those harder to reach low side ports that were previously difficult to reach with a shorter 12 inch hose.
- 10 MINUTE INSTALL - Easy instructions are included and will take as little as 10 minutes to complete.

I had my 2018 Ford Expedition Max to the dealer 3 times in summer of 2018 & 2019 for AC issue. The AC randomly would stop working. I gave up om bring it back to the dealer because they keep telling me they could not find any issues. I just had it to a dealer for a grinding noise in the front wheel. They had my vehicle for 3 weeks I never asked them to look at the AC. They replaced the entire AC as per a special Ford code 18N01. Ford is not notifying customer of this issue. Why didn’t the dealer know this manufacture defect earlier ? For the last two summer I avoid taking people somewhere in my truck do to this issue. Shame on Ford they knew the problem
