Leak Saver FAQ and Technical Information

The Leak Saver works similarly to how blood works in your body. After injecting it, the sealant travels through the system 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 is able to seal small refrigerant leaks where the complete charge is not lost within 7 days.

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

This being said, we have clients who have sealed 48 hour leaks with our product. However, we would give it less than 50% chance.

Why do we measure a leak size in time instead of diameter like some of the other competitive products? We do this because we do not believe it is practical (or even possible?) to physically measure a pinhole leak in the field. The easiest and most practical way to determine a leak size is by how long it takes for the refrigerant to leak out.  

The Leak Saver has 1/4" male and female connections that are common on HVAC and refrigeration systems. Both ends have valves that need to be activated in order to push the sealant in. 

For certain 410a systems, you may need a 410a 5/16" to 1/4" adapter. For automotive systems, you will need a 134a to 1/4" low side adapter.

The Leak Saver is compatible with the following systems:

HVAC Systems: Window Air Conditioners, Ductless Mini-Splits, Split Central Air Conditioners, Packaged Units, VRF Systems, Chillers, and more.

Refrigeration Systems: Refrigerators, Dehumidifiers, Walk In Coolers, Freezers, Home and Commercial Appliances, Supermarket Racks, and more. 

Automotive Systems: Passenger Vehicles, Trucks, Refrigerated Containers, RV's, Boats and Marine, and more. 

The Leak Saver is compatible with all refrigerants except Ammonia. Compatible refrigerants include: R410A Freon, 134A, R22, R404, R507, R290, R600A, and more. 

The Leak Saver is safe for all types of coils, expansion valves, and manifold gauges.

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 a competitor's leak sealant 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. For systems suspected to have air and moisture, we recommend first using the Leak Saver Dry moisture remover or using the Leak Saver Ultimate 3 in 1 complete treatment.

In general, leak sealers are sold widely all over the world without problems when installed properly and with the system in the appropriate working condition. The main difference between our product and others are our highly concentrated and proven formula, easiest injection method, and guarantee. 

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.

Alternatively, you can use the Leak Shot Pro or Leak Shot Automotive injection kit.

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. 

NOTE: This product will only seal small leaks where the refrigerant charge in the system lasts at least 7 days. 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 LEAK SAVER 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 LEAK SAVER.  

STEP 3: Briefly open the High Side Manifold Valve to inject the LEAK SAVER 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 LEAK SAVER tube and discard or recycle. Let the system run for at least ONE HOUR to allow sealant to fully circulate.

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 LEAK SAVER.  

STEP 3: Briefly open the Low Side Manifold Valve to inject the LEAK SAVER 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 at least ONE HOUR to allow sealant to fully circulate.
