Leak Saver Direct Inject Small System with UV Dye - Refrigerant Leak Sealer - Detects Large Leaks - Ideal for Most Small Home Appliances and HVAC Systems up to 1 Ton - Proudly Made in The USA

Great product. I've been able to fix a small leak in our house ac system... I was having to add R22 to the house every 3 months or so. Its been a year and its still working great. Also, I've used the smaller vials to fix several vehicles at my auto repair shop. Its fixed 3 and a 4th the leak was to large for the stop leak to work, but the dye told me exactly what to replace.

Très bon pro… Je l’utilise assez régulièrement

Fonctionne à merveille, c'est mon 4e achat et je le recommande a 100%

I used this on an Active Aqua AACH25 chiller that I use for fermentation temp control in my home brewery. The chiller developed a leak after 2 1/2 years and wouldn't cool. I was about to drop several hundred $ on a new chiller when I found some YouTube videos showing how to add refrigerant to small refrigerators. I used the Supco BPV31D bullet piercing valve to tap into the low pressure side freon line and refill the R134A refrigerant with a can tap and gauge (all purchased on Amazon), but after 4-6 weeks the freon pressure was low again so I was happy to find this product. The female end of the Leak Saver connected directly to the BPV31D, and the hose for the can tap and gauge connected directly to the male side of the Leak Saver UV. With the chiller turned off, I had enough pressure in the system to do a brief purge of the connection between the leak saver and the BPV, and then purged the connection between the can tap / gauge hose and the leak saver with freon from the can. I then pressurized the hose from the can with the BPV closed, closed the valve to the can and opened the valve on the BPV. That's all it took to empty the Leak Saver UV into my chiller's freon line. I powered up the chiller and proceeded to top off the freon to the desired pressure right through the leak saver, let the system run for an hour, closed the valve on the BPV and butttoned everything back up. It's been 2 weeks, the chiller is working great and the compressor is running quieter than ever. I will update this review in a few months to report on whether my slow leak was fixed with the Leak Saver UV.

good product
