Leak Saver Direct Inject AC Refrigerant Leak Sealant 3-Pack - for Most HVAC Systems Up to 5 Tons - Professional AC Leak Sealer - AC Stop Leak Updated 2023 Formula - Works with All Refrigerants

I luv my refrigerator & I don't want to have to replace it, but the freezer isn't as cold as it should be. We're hoping this sealant will plug any leaks we may have. Fingers crossed.

I’m a little shocked but I think this stuff actually works. I’m not an AC tech but I have used it on several different units and the refrigerant seems to be holding on all of them.

Couldn’t find a slow leak in my refrigerator, so I tried this product, so far so good

I refurbish small sealed-system refrigeration appliances; e.g., mini-fridges, wine and beverage coolers, kegerators, ice machines. These small refrigeration appliances are rather notorious for failing to cool after just a few years of use; and I typically collect such from folks grateful to be rid of a bulky and seemingly useless cube. I then attempt to repair the things.Small sealed-system refrigeration appliances are not terribly complicated devices. In most cases I discover a small leak (usually in a soldered joint) and I apply the appropriate repair. After a few weeks of evaluation, I then sell the thing for a nice profit.Instances where I determine a leak is inaccessible or otherwise indeterminate, I inject a shot (or two) of Leak Saver Small System Refrigerant Leak Sealer followed by the usual refrigerant recharge procedure; I then evaluate the operation of the appliance for a month or so.I don't have success with the Leak Saver product 'every' time; but I’ve had enough success using the product in my very specific application that I am content with the brand, and satisfied with its efficacy to do what it claims.

I have tried leak sealers packaged with R134a cans and found they don't work for very long.My 12 year old Bosch refregerator started to deteriorate over a month and freezer would be at 40F. I installed a Supco BPV31 bullet valve on the compressor fill line and recharged with 7.4 oz R143a (measured with before and after using a postage scale) to suction pressure on 2 pounds. Recommended charge is 7.76oz on R134a so was nearly empty. After a month and half it was back to 24F in the freezer.I added the 1 ton Leak saver and recharged to 2 pound pressure on suction line which took 6.3 oz.Now 6 months later freezer is at set point of 0F.
