As a small company, EVERY SINGLE CLIENT is important to us. Our products have been proven in over 20 years of sealant testing and we stand behind them 100%. Your COMPLETE SATISFACTION is our priority. 

If you have any issues with our products, please don't hesitate to reach out to us at info@leaksavers.com. We will make it right!

NOTE: This product will only seal leaks where the refrigerant charge in the system lasts at least 72 Hours. Not recommended for systems that hold less than 10oz of refrigerant. Professional use only. Use only as directed.

STEP 1: Turn the system on and make sure the compressor is running. If it is a heat pump, make sure it is in COOLING mode. BEFORE ANY OTHER CONNECTION, IT IS IMPORTANT TO FIRST connect the female fitting of the LEAKSAVER to the Low Side Service Port of the system. 

STEP 2: Make sure both valves on the manifold are closed. Connect the High Side Hose (Red) to the High Side Service Port. Briefly open the High Side Manifold Valve to purge the hoses and then quickly connect the Center Hose (Yellow) to male fitting of the LEAKSAVER.  

STEP 3: Briefly open the High Side Manifold Valve to inject the LEAKSAVER into the system. As soon as the tube is clear, close the High Side Manifold Valve. Wait one minute for the gauges to equalize and then disconnect the empty LEAKSAVER tube and discard or recycle. Let the system run for at least ONE HOUR to allow sealant to fully circulate.

NOTE: This product will only seal leaks where the refrigerant charge in the system lasts at least 72 Hours. Not recommended for systems that hold less than 10oz of refrigerant. Professional use only. Use only as directed.

STEP 1: Turn the system on and make sure the compressor is running. If it is a heat pump, make sure it is in COOLING mode. BEFORE ANY OTHER CONNECTION, IT IS IMPORTANT TO FIRST connect the female fitting of the LEAKSAVER to the Low Side Service Port of the system. 

STEP 2: Make sure both valves on the manifold are closed. Connect the Center Hose (Yellow) to the Refrigerant tank. Briefly open the Low Side Manifold Valve to purge the hoses and then quickly connect the Low Side Hose (Blue) to male fitting of the LEAKSAVER.  

STEP 3: Briefly open the Low Side Manifold Valve to inject the LEAKSAVER into the system. As soon as the tube is clear, close the Low Side Manifold Valve. Wait one minute for the gauges to equalize and then disconnect the empty LEAKSAVER tube and discard or recycle. Let the system run for at least ONE HOUR to allow sealant to fully circulate.

STEP 1: Turn the system on and make sure the air conditioner compressor is running. BEFORE ANY OTHER CONNECTION, IT IS IMPORTANT TO FIRST connect the female fitting of the LEAK SAVER to the Low Side Car Adapter. Connect the Low Side Car Adapter to the Low Side A/C Service Port of the car. 

STEP 2: Make sure both valves on the manifold are closed. Connect the Center Hose (Yellow) to the refrigerant tank. Briefly purge the hoses and connect the Low Side Hose (Blue) to the male end of the Leak Saver. 

STEP 3: Briefly open the Low Side Manifold Valve to inject the LEAKSAVER into the system. As soon as the tube is clear, close the Low Side Manifold Valve. Wait one minute for the gauges to equalize and then disconnect the empty LEAK SAVER tube and discard or recycle. Let the system run for 30 MINUTES TO ONE HOUR to allow product to fully circulate.

NOTE: You can also use refrigerant can with a can tap to push the Leak Saver into the system. However, it must have a 1/4” hose to connect to the male end of the Leak Saver.

Wear personal safety protection (protective glasses, gloves, etc). Do not bend, cut or deform Leak Saver tube. Do not let refrigerant spray on your skin. It may cause frostbite. DO NOT INGEST THE LEAK SAVER. This product is designed only for use by certified HVAC technicians.

The Leak Saver sealant travels with the REFRIGERANT to rapidly find and seal small leaks. The sealant formula reacts with the moisture and air present at the leak point to make a permanent seal. 

The Leak Saver will seal leaks in systems where the refrigerant charge is not lost within 7 days.

The Leak Saver can be used in the following types of systems:

All Classes of Air Conditioners

All Classes of Refrigerations and Refrigeration Units

Cars

The Leak Saver is compatible with all refrigerants and safe for all types of coils, expansion valves, and manifold gauges. We do not recommend using this product in systems that hold less than 10oz of refrigerant. 

Yes. The Leak Saver is safe for all tools, expansion valves, and cap tubes. 

The Leak Saver is compatible with all refrigerants except ammonia. It is compatible with all oils.

The Leak Saver is unique in the following ways:

BEST FORMULA: 

This is the ULTIMATE version of a PROVEN sealant formula that has been refined over a decade of sealant research. This sealant formula has sealed more than a MILLION leaks. Cheaper competitors (and even some more expensive ones!) reduce their costs by skimping on the expensive active ingredient and replacing it with cheap fillers. Selling direct to you online allows us to sell you the BEST VERSION of this formula. 

EASIEST INJECTION METHOD:

We packaged our sealant into the EASIEST, NO FUSS injector (Patent Pending). You can even install this with ONE HAND (see Installation Method 3). This is MUCH EASIER than the complicated and difficult syringe contraptions and delicate pressurized cans/hoses. 

GUARANTEE:

We are so confident in our product that we GUARANTEE that the Leak Saver seals your leak or the next one is free! (Must be installed by a certified HVAC techs) 

This sealant formula in the Direct Inject format has sold more than 3 MILLION units since 2015 (primarily to HVAC Professionals). The proven formula has been refined over a decade of sealant research to be completely safe for all systems, refrigerants, expansion valves, and manifolds. 

In the cases where we have seen leak sealants (NOT THE LEAK SAVER) damage a system, they were where the home owner injected multiple cans of cheap brand leak sealants into systems that were fully contaminated with air and humidity.

In general, leak sealers are sold widely all over the world without problems when installed by professional HVAC technicians. The main difference between our product and others are our highly concentrated and proven formula, easiest injection method, and guarantee. 

No! No more pump downs needed!

If we sold you a Fractional to 1.5T version of this product, we would just be adding more filler and reducing active ingredients since the volume of the injection tube is always the same. The active ingredient is what you are paying for and it has no adverse effects while circulating in the system. 

The total amount of material inject into the system is around 2grams and is suitable for even small refrigeration systems.

Yes! You can inject multiple Leak Savers into larger systems.

We don't recommend using this product on systems that hold less than 3oz of charge.

Yes! You will also need an Automotive Low Side Quick Coupler (connects to the female end of the Leak Saver) and a manifold gauge with 1/4" hoses (connects to the male end). 

To use with a refrigerant can with can tap, you will need to make sure your hose has a 1/4" connector to connect to the male end.

The term "polymer" was created by a competitive leak sealant formula manufacturer to try and scare clients into buying their product. If you look at our Safety Data Sheet, we openly disclose our ingredients (however, the exact mixture of these ingredients is a trade secret!). Our formula has been proven to work without damaging systems for the past 20 years. If you look at some of our competitors' Safety Data Sheets, they might not even tell you what they put in their sealant. It makes you wonder what they are hiding! 

Our sealant formula functions similarly to the blood in your body. While circulating in the system, our product is NOT a polymer and has no adverse effects. Just like blood, when it encounters a leak, it joins together to plug the hole and stop the leak. 

Yes!

Unlike other competitive products, the Leak Saver does not degrade in the system. The sealant remains unreacted in the system to prevent future leaks. Since the amount of sealant injected into the system is minimal, it does not affect the functionality of the system. 

First, please make sure you had followed the instructions correctly and that the refrigerant charge in the system does not disappear within 72 hours. If it leaves in less than 72 hours, the hole may be much too big.
