Review: Saved me $3000+ - Used this to repair 7 year old mini-split system in a recently purchased house. The AC company wanted over $3000 for a new system, said the system I had couldn't be repaired. Granted it is an inexpensive no-name mini-split system from China with aluminum condenser and evaporator. I understand why they don't repair these - you never know which component will fail next - or when. I bought this, an inexpensive set of gauges, and a bottle of R410 and had it fixed in a few hours for a few hundred dollars. That includes the time spent watching YouTube videos. Over a year later and it still going strong. Review: Worked Great - Used on a minisplit system with a small undetermined leak. The system still had pressure, and had leaked down slowely over several years. Simply attached to the service port, attached gauges, and brought system up to the correct level of 410a through leak stop. Has worked well now for a couple months. ## Features - APPLICATION: AC Leak Freeze PRO refrigerant leak sealant with new leak seeking nano particles creates a stronger dual sealant; nano particles are non-polymer and non-reactive technology that fills cracks and imperfections in hvac coils - EASY APPLICATION: Standard 1/4" AC leak freeze adapter; ready to use and safe for HVAC systems; OEM approved and professional install is recommended - STOP LEAKS PERMANENTLY: AC leak freeze will stop leaks of refrigerant gas in HVACR air conditioning and refrigeration systems in homes and commercial buildings; AC leak freeze revitalizes AC and refrigeration systems by permanently sealing small, hard-to-find micro leaks - SPECIFICATIONS: .05 oz leak freeze cartridge; polymer free, non-flammable and non-toxic; OEM approved and safe for HVAC systems - FOR THE TRADESMAN: RectorSeal is recognized as a leading provider of quality solutions for the professional trades serving heating, ventilation, and air conditioning (HVAC/R), plumbing, electrical, and construction markets ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #199,909 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #609 in Hardware Sealers | | Customer Reviews | 4.1 out of 5 stars 12 Reviews | ## Images ![AC Leak Freeze 45308 Leak Sealant, Easy Application, HVAC, 0.5 oz. - Image 1](https://m.media-amazon.com/images/I/91djBX9SGNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved me $3000+ *by T***E on August 30, 2023* Used this to repair 7 year old mini-split system in a recently purchased house.
