## Overview

Leak Saver Direct Inject UV is a professional-grade refrigerant leak sealer with added UV dye for easy leak detection. Designed for systems up to 5 tons, it works with all refrigerants and uses a direct injection method for mess-free application. Trusted by HVAC technicians and over 3 million users since 2015, it permanently seals small leaks and helps identify larger ones, ensuring long-lasting system efficiency and peace of mind.

## 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.

Review: Back in 2020, I had three R22 units that had low refrigerant. One was so low it was icing up. The service tech said R22 is EXPENSIVE so I could try recharging them with leak stop, but that would cost thousands of dollars and might not work. On the other hand, I could buy all new systems. I decided to fix them myself with some help from a friend in the industry. I was able to buy the R22. I then researched the leak stop products and found that one of the things I needed to make sure and do is add a moisture remover before adding the leak stop. I add the moisture remove and the leak stop in all three of my systems and have not had any problems since. I highly recommend this product.
Review: This is the second batch of Refrigerant Leak Sealers that I've used. I was losing a lot of freon from 2 systems. The initial treatments stopped the leaks almost completely. After a couple of years, one system started to leak a little. Another treatment stopped that as well. Now it's several years later and another treatment has boths systems working great and leak-free. The HVAC company charges $100-$150 per treatment for a very similar product. My builder-grade AC systems are almost 20 years old. Ours is the only home in our development that hasn't had to replace the AC systems. You do need a a basic manifold gauge set or injection kit, but it's simple to use.

## 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.
- More Than 3 Million Units Sold Since 2015: 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.
- With Added UV Dye for Finding Large Leaks: Seal it or find it! If you have a leak that is simply too large for leak sealants to seal, the added UV Dye will light up brightly at the leak site when using a UV flashlight.
- Compatible With All Systems and Refrigerants: 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. It also works with all refrigerants including R410A Freon, R22 and replacements, R134A, R1234yf, R404A, R290, R600a, 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%.

## 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. If you are not completely satisfied, please reach out to us directly and we will make it right. With more than 4 million units of this formula sold since 2015, we have a strong track record of effectiveness.
