Restores Maximum Cold A/C Pro® Extreme Conditions Smart Charge A/C Recharge Kit helps make recharging your vehicle’s air conditioning easy and affordable. This car A/C leak sealer includes a proprietary formula that seals rubber leaks in O-rings, gaskets, and hoses, and protects your A/C system while providing 2x cooling boosters versus the next leading brand of automotive A/C refrigerant recharge kits. This A/C refrigerant features a digital A/C gauge that uses Smart Charge technology, with a reusable trigger-style dispenser that wirelessly connects to your smartphone using Bluetooth technology through the A/C Pro® App (available on the Apple App Store and Google Play) to provide you with guided, adaptive vehicle-specific instructions to help eliminate guesswork during the recharge process. Each A/C refrigerant uses a robust ingredient combo designed to withstand high pressure seen with frequent A/C stops and start-ups, as well as protect against extreme temperatures and high use. This A/C refrigerant recharge kit also comes with an A/C charging hose for easy use. Simply find the low-pressure port, measure the A/C system and charge. Nothing cools like A/C Pro®.
The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condenser on the low pressure (suction) side of the system. R-134a recharge hoses will only fit on the low side service port on all R-134a vehicles and R-12 vehicles that have been converted to R-134a. If you don’t know where your low side port is, you can try using our low side port finder.
The only fitting that the standard recharge equipment will fit is the low side service port.
The EPA requires that ANY replacement refrigerant MUST have unique fittings, charging devices and label. Therefore, the EPA states that “drop in” refrigerants are illegal. Furthermore, only R-134a has been tested and approved by the original equipment manufacturers.
No. Federal law prohibits topping off an R12 system with a different refrigerant. Your options are to locate some R12, however you must be certified to purchase, and add it with an R-12 recharge hose. Or you can convert the system using one of our R-134a retrofit kits that will allow you to now add 134a refrigerant to your automotive air conditioning system. You will have to make sure that you remove any residual R12 by having it evacuated prior to retrofitting your vehicle.
