It permanently seals small refrigerant leaks by chemically reacting with moisture and air at the leak site. Compatible with nearly all refrigerants and oils (except ammonia), it offers a fast, mess-free injection method favored by HVAC technicians. With over 3 million units sold since 2015, Leak Saver is the trusted choice for reliable, long-lasting leak repair across residential, commercial, and automotive cooling systems. ## Description No more messy syringes, fussy hoses, or pressure sensitive cans. The Leak Savers Direct Inject Sealer will provide fast, effective sealing for your refrigeration system. Use a single or use it in multiples for larger systems. Proven Formula: The concentrated formula means less material floating around in your refrigeration system for a more fluid transfer. Travels with the gas for a faster and more effective seal on your leak. It can be just as successful for you as it has been for the over one million systems applied to. System requirements/Usage instructions: For systems up to 5 tons (60,000 BTU). Use it for permanent sealing on both small and large refrigerant leaks, and prevent future leakage. Product Details: Works with all types of refrigerant (Freon 410A, R22, 404A, 134A, etc.). If the leak does not empty the system within 72 hours, the Leak Saver should seal the leak. Safe for manifold gauges, expansion valves, or capillary tubes. For use in split systems, mini splits, packaged units, micro-channel coils, heat pumps, commercial unit coolers, refrigeration systems and more. Note: Not for use in ammonia systems. Not recommended for systems holding less than 10oz of refrigerant. ## Features - The Easiest Injection Method: No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver injects directly and easily into the system with a basic manifold gauge set or even easier with our Leak Shot Injection Kits. Note: for automotive systems, you will still need the standard 134A to 1/4” charging adapter. Mini-splits may require a 5/16” to 1/4” charging adapter. - A Permanent Fix For Leaks: The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It’s similar to how blood in your body reacts to a cut. When a leak occurs, the Leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks. - Over Three Million Units Sold: With over 3 million units sold of this sealant formula since 2015, we are the most reliable leak sealant among HVAC professionals. Super concentrated and made to work with all types of refrigerants, it’s compatible with all types of refrigerants and oils (except ammonia). - Made By HVAC Professionals: And used by them. Use Leak Saver on the following systems: central AC, mini split AC, cassette AC, car, refrigerated truck, home refrigerator, commercial refrigerator, boat, rv, ice machine, refrigeration racks, chillers, refrigeration condenser, cold rooms, and more. - The Product We Trust: Our company is owned and operated by HVAC technicians. These are the same products we use in our own jobs, and stand behind them 100%. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075KKLGHS | | ASIN | B075KKLGHS | | Brand Name | Leak Saver | | Color | Green | | Customer Reviews | 4.1 4.1 out of 5 stars (82) | | Customer reviews | 4.1 4.1 out of 5 stars (82) | | Date First Available | 23 May 2018 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 16.5 x 10.2 x 24.1 centimeters | | Item model number | LS-05 | | Manufacturer | Leak Savers | | Manufacturer | Leak Savers | | Material Type | Polymer | | Model | LS-05 | | Part Number | LS-05 | | Product Dimensions | 16.51 x 10.16 x 24.13 cm; 430 g | | UPC | 604296227662 | | Unit Count | 6 Count | ## Product Details - **Brand:** Leak Saver - **Item dimensions L x W x H:** 16.5 x 10.2 x 24.1 centimeters - **Material:** Polymer - **UPC:** 604296227662 - **Unit count:** 6 Count ## Images ![Leak Saver Direct Inject Refrigerant Leak Sealer, 6 Pack - 2022 Updated Sealant Formula for Most HVAC Systems Up to 5 Tons - Made in the USA - Image 1](https://m.media-amazon.com/images/I/71zGe3rF+fL.jpg) ![Leak Saver Direct Inject Refrigerant Leak Sealer, 6 Pack - 2022 Updated Sealant Formula for Most HVAC Systems Up to 5 Tons - Made in the USA - Image 2](https://m.media-amazon.com/images/I/71w8UUKIWpL.jpg) ![Leak Saver Direct Inject Refrigerant Leak Sealer, 6 Pack - 2022 Updated Sealant Formula for Most HVAC Systems Up to 5 Tons - Made in the USA - Image 3](https://m.media-amazon.com/images/I/815RYydwVSL.jpg) ![Leak Saver Direct Inject Refrigerant Leak Sealer, 6 Pack - 2022 Updated Sealant Formula for Most HVAC Systems Up to 5 Tons - Made in the USA - Image 4](https://m.media-amazon.com/images/I/71nvKBqYRVL.jpg) ![Leak Saver Direct Inject Refrigerant Leak Sealer, 6 Pack - 2022 Updated Sealant Formula for Most HVAC Systems Up to 5 Tons - Made in the USA - Image 5](https://m.media-amazon.com/images/I/81S17EMO02L.jpg) ## Questions & Answers **Q: Will this work with my system?** A: The Leak Saver works with all air conditioner and refrigeration systems. It is compatible with all refrigerants (except ammonia) and is compatible with all oils. **Q: How does the Leak Saver work?** A: After injection, The Leak Saver sealant circulates throughout the system with the refrigerant. If there is a small leak, the sealant reacts with the moisture and oxygen at the leak site to form a permanent "scab-like" seal. **Q: What do I need to install the Leak Saver?** A: To inject the Leak Saver, you will need either a basic set of manifold gauges or our Leak Shot injector. When using it with automotive systems, you will need a 134a to 1/4” adapter. Ductless mini-split systems may require a 5/16” to 1/4” adapter. **Q: What size leak will the Leak Saver seal?** A: The Leak Saver is able to seal small refrigerant leaks where the complete charge is not lost within 7 days. If this is not possible, your leak is too large to be repaired with Leak Saver. **Q: What do I do if it doesn’t work?** A: We stand behind the effectiveness.
