The Leak Savers Direct Inject For systems up to 5 Tons (60,000 BTU). **PROVEN FORMULA** This is the same sealant formula proven in over ONE MILLION successful applications! It seals small refrigerant leaks permanently and prevents future leaks. **EASIEST APPLICATOR** Just CHARGE it in! No more messy syringes, fussy hoses, or pressure sensitive cans. The Leak Saver can also be used in multiples for larger systems. **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 will typically seal the leak. Super concentrated (less material in the system). Travels with the gas to seal leaks faster and more effectively. 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 that hold less than 10oz of refrigerant.

I am a HVAC service tech and we get calls every week to fix refrigerant leaks. Me and my guys use these for slow leaks that are hard to find. Works great. After the first time trying these direct injects they were the only ones our guys wanted to use. Easiest leak sealer to inject by far.
2 years working with these now. I’ve even seen it fix a system with multiple small leaks.
Original submission: Tried using this per the included instructions. First tried putting it between the 410 tank and low side. No 410 would flow and the fluid in tube was static. Took the “leak savor” out of the system and filled it with 410 up to the prescribed amount by the manufacturer. Then turned off the compressor and inserted this thing between the gauge and low side. Turned on compressor and carefully opened hi side to try and force the fluid from the tube (per the instructions!). No effect! Then, thinking maybe this “leak saver” may be directional in operation... I turned off the valves both sides and the compressor. Then reinserted this thing into the hi side hose but now in the reverse direction. Turned the compressor back on and opened the high side valve again...no change. While picking up the leak saver one of the ends loosened slightly and then the tube became empty real fast! Don’t think anything went into the HVAC systems but I did lose about 25 psi on the high side. The pressure difference in the system was around 250 psi when trying to empty the tube; 360 when the connector loosened slightly. Based on the directions, the pressure needed to force the fluid from the tube should be around 100 psi or so. However, by accident I found that it would empty when it exceeded 300 psi! Now I have to find an alternate solution and reconnect the 410 to add a bit more to the HVAC system.
