Product Description

The A/C Pro® Ultra Synthetic refrigerant kit features a specially designed formula that helps a vehicle’s air conditioning produce the coldest air. Approximately 17 oz. of R-134a and 3 oz. of additives are used to recharge a vehicle’s A/C system, seal common leaks in the rubber components, and protect and extend the A/C system’s life by eliminating acid and moisture build-up.

This #1 selling A/C recharge kit (according to NPD 2019) comes with a reusable extra-long braided charging hose and gauge. A/C Pro® R134a refrigerant offers a simple and effective way to keep your car cool.

  • Comes with reusable extra-long braided charging hose and gauge with trigger dispenser for easy, convenient, and accurate recharging.
  • Specially designed formula with 2X cooling boosters vs. the next leading brand of A/C recharge kits – independently tested to deliver the coldest air from your vehicle’s air conditioning system.
  • Contains leak sealer to seal common A/C leaks in rubber hoses, gaskets, and O-rings.
  • Protects and extends air-conditioning system life.

Usage Directions

1. Open hood and find low-pressure A/C service port

With the engine off, open the hood and locate the low-pressure A/C service port (on the larger diameter tubing, between the compressor and evaporator). Remove the plastic cap from port and keep it safe for later.

For Best Results: Charge under the shade. Keep the car doors open while charging (front and back).

2. Turn engine on and turn A/C on high

Start the car and turn on A/C. Set fan to highest setting and temperature to coldest setting. Make sure recirculation mode is selected.

3. Attach APC-100 quick connect fitting

Attach quick connect fitting on the end of ACP-100 recharge hose to low-pressure service port identified earlier by pulling the connector ring back as the fitting is pushed on.

Note: Our quick connect fitting will attach only onto the low-pressure port.

4. Read pressure color

Without pulling the trigger on the ACP-100, look at the gauge to see what color section the needle is pointing toward. Depending on the color, determine next step according to the grid below:

5. Remove plastic spacer

Disconnect the trigger assembly from service port. Unscrew and remove plastic spacer between trigger assembly and can.

6. Recharge A/C with APC-100

Shake can well and screw can onto gauge/ trigger assembly. Connect the quick connect back on the low-side port. Make sure to always hold the can upright (12 o’clock position) before starting to charge. Squeeze the trigger to charge the A/C system. While charging, shake the can up and down, alternating between 12 o’clock and 3 o’clock position. Every 10–15 seconds release the trigger. After needle is stabilized, check pressure readings on gauge.

For Best Results: Read pressure when the trigger is released, not while being squeezed. It is typical for the gauge to bounce around as the compressor is cycling. If that happens, read the lowest pressure.

7. Stop charging when the needle is in green


Once the needle makes it anywhere in green zone of the gauge, charging is complete.

Do not try to get it to the highest part of the green zone or you risk overcharging. Remove hose from service port and replace plastic cap when finished.

Store any unused refrigerant in a cool, dry place, with charging hose securely attached to can.
