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: : The Leak Saver UV is compatible with all systems, refrigerants (except ammonia), and oils. It is great for central air conditioners, car and automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils and more.

The best freon leak sealant brands

One of the things we suggest to most of our readers is to buy the freon leak sealant from a well-known brand. Good brands provide, good quality products, great customer support, and have service centers in different places around the country. Regarding the freon leak sealant I have a preference for the products of the brands listed below.

  • Leake Savers
  • Interdynamics
  • Leak Savers
  • Interdynamics
  • Leak Saver
  • Thermofluid Technologies
  • Enviro-Safe
  • 5 Things You need to consider when choosing the freon leak sealant

    There are some things you should consider when buying a freon leak sealant. We spent 22 hours researching the most important things you should consider when buying a freon leak sealant. So should we start with the list of things you should consider?

    1. Budget and price matching

    Make a list of the things you want in your freon leak sealant and the price you are willing to pay for it. So try to look for a product in that price range and choose the one that appeals to you the most. One tip we would like to give you is: don’t settle for a cheaper product if it doesn’t even have a function you need.

    Most freon leak sealants fall within the price range of $ 34.95 to $ 31.79. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the Leak Saver: Direct Inject UV – Refrigerant Leak Sealer with Added UV Dye to Detect Large Leaks – For AC, Refrigeration, and Automotive Systems Up to 5 Tons – Compatible with All Refrigerants.

    If you want something medium range, choose AC Pro Car Air Conditioner R134A Refrigerant Stop Leak Kit, For Rubber and Metal Leaks in O Rings and Hoses, 3 Oz, MRL-3. If you have a very low budget, you can choose the one that is the Enviro-Safe Proseal XL4 and R12/22 Charging Hose w/Tap #9820

    2. Does it have all the features you need?

    Most importantly, the freon leak sealant you are purchasing should have all the features you are looking for. In case you don’t even have one, don’t buy! We are saying this because you will not be able to use it for that purpose. If you are a person without budget problems, I would suggest you to choose the best model which is Enviro-Safe Proseal XL4 and R12/22 Charging Hose w/Tap #9820

    3. The brand

    Buying the freon leak sealant from a reputable brand can actually make sense. Not only will it be better than others in terms of “build quality”, but it will also have some extra features, better customer support. Famous brands have multiple service centers across the country, so if you have any problems you can simply take your freon leak sealant to one of their service centers.

    4. Warranty Matters!

    When you buy a freon leak sealant from a well-known brand, you will get a guarantee. Low-cost products also come with warranties, but the claim process could be tougher. That’s why I always suggest you buy the product from a reputed brand and the one that comes under warranty. It will save you from repair costs in the future. On average, around 21% of people end up paying 40% of the product price for the service! You can save on service costs if the product is under warranty!

    5. Check out our website

    On our website we have experts in all categories and no matter what the product is, we have a better review or list about it. The products on our list are based on expert picks, advice and hours of research. That’s why when you buy something that’s listed on our best list, you won’t regret it.
