Direct Inject UV Small System

LEAK SAVER DIRECT INJECT UV - FOR SYSTEMS UP TO 1 TON (12,000 BTU, 3.5kW) - Perfect for Small Appliances - NOW INCLUDES ADDED MOISTURE REMOVER!

• NOW WITH ADDED UV DYE - 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.

• THE MOST TRUSTED - The numbers don’t lie! With more than 3,000,000 units sold of this sealant formula since 2015, we are the most trusted leak sealant among HVAC professionals. Proudly made in the USA. We believe in the effectiveness of our product and stand behind it 100%.

• PERMANENTLY SEALS LEAKS - The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 7 days. It works similarly 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. 

• WORKS WITH ALL SYSTEMS - Our product is compatible with all systems, refrigerants (except ammonia), and oils. It is great for small central air conditioners, refrigerators, ductless mini-splits, dehumidifiers, 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 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 - The Leak Saver is safe for all manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system.
