ZeroR Performance Boost Kit for R1234YF Refrigerant AC Systems | 24" Charging Hose with Gauge | 3 Cans
- 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.
