What I have found is that this runs a tight 1st place with the "top of the line" leak sealers on the market. If you know how to properly install this, it is easy to use and the application is simple. It can save professionals a lot of money that can be transferred in lower invoicing for long-term clients, leading to retaining clients at a fair price. It is not a "cure all", meaning it works as designed but will not seal large leaks beyond design so if the leak persists after application then the fault is too large and will need mechanical replacement of lines or parts. As an aside, I have never once experienced clogging of any cap tubes when using this product but have had good success in saving my clients large amounts of money in times of uncertainty. Hence the reason why I prefer this brand. Thumbs up!!! and 5 stars!!! Review: Inexpensive self help repair - Did the job perfectly, and was simple to use. Very cost effective for sealing leaks, and saved me about $1200.00 in parts and labor it would have cost me to have a HVAC company to make the repairs, although to use it, you do need some basic knowledge and skills, along with some necessary tools, equipment, and supplies. As far as durability, only time will tell the story on that, but it has been several days now, and my system is still functioning as it should and there have been no issues to this point. Extremely pleased with results so far. Very highly recommended product. ## Features - STOP LEAKS PERMANENTLY - The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 7 days. 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 - WORKS WITH ALL SYSTEMS INCLUDING CARS - Our product is compatible with all systems, refrigerants (except ammonia), car refrigerants, and oils. It is great for central air conditioners, automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils and more. It also works with all refrigerants including R410A Freon, R22 and replacements, R134A , r1234yf, R404A, R290, R600a, and more - STRAIGHTFORWARD INSTALLATION - No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver HVAC sealant 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. You can see our straightforward installation videos below - SAFE FOR ALL TOOLS AND PARTS - Our HVAC leak sealer is safe for all manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system.
