Worked for me.

I used this product on a 23 year old R22 system that had a very slow leak. I had to add some about every year but since R22 is so expensive now I didn't want to do that anymore. This product did seal my leak and the leak dye did show me 3 locations where I was leaking from which were so small a leak detector or bubbles wouldn't even show. I doubt this stuff would seal a major leak but the dye would at least show you where you are leaking from. System has been running now for about 2 months with no leaks

Stopped a slight leak

This appears to have saved my 3 zone diy project. I installed this preemptively just to protect from future leaks. One of my 1/4 connections (which I followed torque spec) has the tiniest green ring around it, so it must have had the slightest leak. This product appears to do its job! Why did you pick this product vs others?:Made in USA

This stuff can work

I say ‘can work’ because I’m not sure it’ll work for everyone. In my situation, the leak was noticeable after about four-five days. I first tried the stop leak without dye, and I still had to recharge after about five days. Recharged about three times with no luck. Decided to try the leak with dye, and that seemed to do the trick. Saw some fluorescent flecks coming out of the evaporator coil, after about six days the AC was still cold and the pressure was unchanged. In the meantime, I bought a complete new unit because I wasn’t sure the stuff would work. It was about time for a new unit anyway, so no issue there. If I had it to do over, I’d get the dye formula first, give it time to work. For some people, this is a lot better than replacing a whole unit.

Works well, just for what it is seems expensive.

Seems to have helped with our residential split system. Was easy to use vs others and can't say if the UV worked as I never found any simye so maybe the leak sealent fixed anything that might have leaked.

Does not work. Stuck valves, and expensive fittings for a one time use??

UPDATE: this week the fridge stopped working again, loss of freon. So this product did not fix the very slow leak as I was hoping it would, so have to give it one star now.For the price, this is not a good value. The expensive brass fittings on each end are not reusable, and obviously jack the price up. The leak I’m trying to fix is in a fridge, and is very slow (2 to 3 months), and I’d expect this product would work, yet it doesn’t.And have not been able to find the actual leak using a black light to reveal the UV dye… frustrating!!Original, initial review:I just put this in today for my Samsung side by side. I did get the leakstop into the fridge today, I’ll come back in a few weeks to report on efficacy.1) package came with no instructions whatsoever… just the stop leak tube in a sealed package, in a branded slightly larger package… I went online for the instructions.2) Installing was challenging. There’s a valve at both ends, and neither activated. The input from the manifold has Schrader valve, but my hose/gauge does not have the fitting to activate it.3) The valve on the other end would not activate when screwed into a bullet piercing valve.I had to unscrew the first Schrader valve completely, connecting the gauge, the contents ended up in the hose, so the hose was the intermediate step…I ended up not using the supplied fancy brass fittings on a mini hose, though not intentionally, simply the valves were not working for me.4) at $46 I wonder how much was due to the nice knurled brass fittings? Is the compound available to refill the tube?Is there a recycling program?5) the fluid tube is very stiff… this became a problem as I had installed the bullet valve pointing straight up last week when I was doing the initial refill with r134a…. So there was not enough clearance between valve and chassis, making attaching challenging due to the stiffness…Wondering what I can do with these nice fittings, LOL…

Good price, great warranty and easy to install!!!

So far, So Good. A/C had a small leak in the coil in the attic. Contractor charged $200.00+ to check the unit and confirmed a leak. They wanted $9,700.00 to replace the complete A/C system. I bought the stop leak and r410a… I put the stop leak and recharged it last week and the a/c is still working so far. Very easy to use and it worked.
