The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. 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. Patent-Pending Easy Direct Injection Installation Method 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.

Review: I've got a slow leak somewhere on my 16 year old r410a 3ton Lennox Hvac - losing about 2lb of refrigerant over 8 months or so. Decided to try this leak saver as a last ditch hail Mary before biting the bullet and replacing the system. Used the charge in with refrigerant method - tube was clear and it was in in a couple of seconds, very simple. Left the tube attached while I topped up the rest of the refrigerant to the correct level. System is currently running great again, heating and cooling as it should. It's only been 3 weeks and given the leak is very slow before it becomes noticeable, it might be a while before I can tell if this has worked or not. I have shined my UV light round the usual suspect leak spots....have not seen any dye. Will check back in in a few months to see how it's doing, fingers crossed at this point!

*by H***P on 12 January 2026*

I think I did over 10 hours of pure, uninterrupted research to find out whether this would clog and destroy my AC system or magically repair it. Here's what I found. For context, I have a newer type of heat pump that uses R-410a (Bosch BOVA36HDN1M120G) paired with an old high-velocity duct system (Unico MC3642HX) *Will this destroy my AC system? What various sources report is that organosilane, polymer-free leak sealants (like this one) are generally safe for new model heat pumps and will not "slug" or otherwise destroy sensitive components in modern machines. Supposedly, this is because they will only react and harden when exposed to the pressure and oxygen variations associated with getting outside of the closed refrigerant loop of your system (i.e., when exposed to an actual hole). Leak sealants (generally) apparently got a very bad rap in the 2000s because they used to be polymer-based which, when introduced into systems like mine, immediately caused problems with sensitive (apparently "microscopic") valves and whatnot that modern heat pumps use to regulate the flow of refrigerant. They can also apparently cause problems when other contaminants like air or water have already entered the system, causing the leak sealant to trigger earlier within the refrigerant line instead of at the leak site, resulting in issues when the refrigerant flow constricts. I agonized about what to do because I had a leak in my system that took 2 years to allow enough refrigerant to escape to make my heat pump lock out (what most would describe as a micro leak). For reference, in my area (a HCOL suburb), multiple HVAC companies said that their go-to in my situation would be to pull all the refrigerant out, separate my system into indoor coil, piping and outdoor unit, and then do a nitrogen test to find the leak. It apparently would take about half a day to do this process, and I was quoted about $200/hr of labor during high-season (December). And that was to find the leak only. Additional costs would then be tacked on for repair which, by the way, if you have an R-410a system like mine, may not be viable if the leak is in your coil because R-410a is being phased out. And even more costs would come into play if the leak wasn't somewhere easily accessible, like inside walls or ceilings. There are some products that apparently can electronically detect leaks, but it was a chore to get HVAC techs (from multiple companies) to even mention this option. I imagine there's some self-interest at play there, but those leak detectors are also available online if you are inclined to try them. Putting all that together, I asked one of the HVAC workers visiting me to give his real thoughts on the sealant. Off the record, he said the official line is that it's not recommended (injecting anything into your refrigerant line will immediately void any warranties you might have on your unit), but that the end result would either a fix or nothing. He said he would advise just refilling periodically, and getting a can of R-410a somewhere (since these are being phased out, with the expectation that prices go up over time, like they did for R-22). I decided to trust in internet research and go for it, and had the tech add in the sealant for me (I saw some videos online claiming that this process was straightforward, but also multiple videos where people added this into the wrong pressure line, resulting in it exploding in their hands, or adding it with too much or too little air). I then ran the system in cold mode for 3 hours, and then ran it at a moderate heating mode constantly since then. The system is still working fine. I don't know if the leak sealant has worked or not, but the system itself has been fine for about a month now. If you decide to take the risk that I did, I suggest you check the SDS sheet for the product you choose. The one for this one is available here (https://www.leaksavers.com/apps/help-center) under the "Leak Saver Installation Help" category, and make sure you are also getting a "polymer-free" organosilane leak sealant as opposed to one of the older polymer-based sealants still floating around (especially at big box stores). Otherwise, good luck. Ultimately, I think this is one of those things that you just have to take a leap of faith on, because all reputable HVAC companies will give you the same party line about this not being an approved product, and all technicians will generally repeat that mantra. The only thing I can say is that it did not immediately kill my system (parts mentioned above).
