ENVIRO-SAFE AC Stop Leak 3-in-1 for R410a and R22 | Refrigerant Leak Sealer, Moisture Remover, UV Dye | Direct Inject | Central AC, Heat Pump and Mini-Split | 1.5 to 5 Ton ProSeal XL4

Features

• MOISTURE INSIDE YOUR SYSTEM IS DESTROYING IT – this is the only product that fixes all three problems at once. Moisture in a refrigerant system mixes with refrigerant to form acid – corroding coils, attacking the compressor, accelerating leaks. If your system has been recharged more than once, moisture is likely the real problem. One inject: ProSeal seals the leak, ProDry neutralizes the moisture, UV dye marks the site.
• WORKS WITH R410a, R22, R32, R454B, R134a AND MORE – all residential refrigerants covered. Compatible with every refrigerant and oil in standard residential systems. Not for ammonia or CO2. For systems 1.5-5 tons. The 3-in-1 is the right choice for any system over 10 years old or in a high-humidity region.
• NO PUMP-DOWN – inject into a running system in under a minute. Connect to the low-side port. Inject using refrigerant or the high side pressure. Disconnect. All three formulas inject together in one trigger pull. No second application. No vacuum pump. Let the system run 45 minutes. Done.
• SAFE FOR TXVs, EXPANSION VALVES, AND ALL OILS – never voided a warranty. Both the sealant and moisture remover are safe for all system components. The dehydrating agent in ProDry converts moisture to synthetic oil – it does not leave residue or void manufacturer warranties.
• THE RIGHT CHOICE FOR OLD SYSTEMS AND HIGH-HUMIDITY CLIMATES – original manufacturer since 2014. If your system is pre-2010, has visible corrosion, or is located in the Southeast, Gulf Coast, or Pacific Northwest – moisture contamination is almost certain. Use the 3-in-1, not the standard. Enviro-Safe has made this formula since 2014. Made in the USA.
