Supco FCR6 Fin Comb Ring

I’m not a HVAC technician but I often have to work on heat exchangers and over time the fins get bashed and bent so I did some research and found these handy little combs. Went through them all, picked the right size and then combed them out straight again. Great purchase!!

Good product at a good price

as a professional in Mechanic, i have already use comb like those and when use correctly and with care, it will straitened the fins. For sure that if the fins are really smashed and pressed-in, there is no tools that will work because the fins would break and tear as you straiten them. Good item to refresh all kinds of fins > car radiators, A/C compressor radiator, window A/C, portative dehumidifier and name it...

I used this to fix up the fins on my home A/C unit. It worked great, using mostly the 16/inch comb. It's not as simple as you would think, but I developed a few techniques that helped, which I will share: 1. You can't just stick it in and run down the fins. Start at a point where the fins are ok, and find the right size comb. Once you have this, gently work it in between the fins. Sometimes two fins will stick together, and that's ok, you can straighten that out on a second pass. Once the comb is in, slowly run it down the rest of the way down. Going up is harder but sometime you need to do it. 2. If it starts to get stuck, wiggle it a bit. Don't force it too much or you'll tear the fins. 3. Sometimes it takes a few passes. Overlap these a few fins. This is a good way to go back and fix two fins stuck together. 4. If it's hard to get the whole comb in, angle it so that only half of it goes in. Sometimes this is an easier way to get started, then the whole comb goes in. I did this a lot. 5. If you have an area where the fins are pushed flat or crushed, you will need to prep it a bit before using the comb. Try to pull some of the fins back out with your fingers (running a finger over the fins usually pulls them out), or use a small screwdriver or utility knife. Pull them up in groups of 3 or 4. You have to get them sticking out a bit before you can run the comb through to straighten them. Don't try to fix it all at once, but start near the outside of the bad area and work your way in, overlapping at least half. It will straighten up. You'll be amazed. 6. You have to have some patience. It took me about 1-1/2 hours to do my A/C unit. But it looks great now. 7. If the A/C (or whatever) has a protective grill over the fins, you'll need to remove that first before working on it. It's very difficult to try to fix it in between the wires of a grill. Often the grill is held on by just a few screws. Then be careful not to damage the fins when reattaching the grill. 8. Once you have this fixed, hose it down to finish the cleaning. But, be careful to spray vertically, not across the fins, or you'll eventually damage the repair you just made. With all the fins straight, it doesn't take a lot of water pressure to clean off the fins. No pressure washers! 9. Sometimes the fins are already torn, or you may tear it no matter how careful you are. The tool will not work over a torn fin--don't try, you'll make it worse. Just work around it. Use a screwdriver or knife to straighten the bad are a bit and move on. 10. It takes some practice to master these techniques. After 15 minutes of working on it, you'll find that all the above tips start to make sense, and you'll get better at it. At first, I thought the plastic tool wasn't going to last more than a few minutes. But it surprised me, and it looks just fine even after straightening the entire A/C unit. I was so pleased that I decided to write this review. Hope this helps.

Being this is the first set of fin combs that I have ever used, I think that it worked great. That being said, who knows how other sets work. Also, I only used one comb in the set. it was the "18 per inch" comb that I used on a 1999 Dodge Ram. If you have an intended purpose for these combs, you will only use the size that is correct for your application. The fins were severely damaged and many were bent flat but I was able to completely straighten everything. I had to start with just a fin or two that were bent and move into the 'dents' a little at a time. I have heard of using soap and water to make it 'glide' through the fins easier. I didn't do this. I did it completely dry. The combs are plastic and probably delicate, but while using them, I was appreciating the material that they were made of. I don't know that I would have wanted anything other than plastic is what I mean. It bent fins at times and at times it got stuck. I could see a comb made of metal causing issues for me. Plastic might be the perfect material to make a fin comb out of. There were times that the combs would bend and I would actually almost make it worst. What I mean is at times, I bent 2 fins together while fixing another issue. (the plastic would get in the fins wrong to begin with) That isn't too much of an issue however since you have a fin comb in your hand. All you have to do is to get the comb in some fins correctly, either above or below the part you just messed up and move it past the part you messed up. That way you can go up or down and fix the issue you just created. (this is my first fin comb experience, that may be obvious to some with more experience) So as long as you have a good section above or below the area that you messed up, you can get it back. (assuming your fins go up and down that is) Overall, it completely fixed the fins on my 1999 Dodge Ram. It is tedious. It does take time and lots of dirt comes out in the process. My comb is really dirty. I found myself combing areas that weren't even bent just to get the dirt out. My next step is to get some soap and water and soak it a bit, then rinsing and spraying it with a garden hose with a pressure nozzle. Getting more surface area for these fins will dramatically improve the performance of the AC condenser. I may use this on my house condenser at a later date if I have a comb that fits.

I read dozens of fin comb reviews and eventually decided that most of the bad reviews are by the class of people who think Scrubbing Bubbles and Swiffer will magically keep your bathroom clean. If you have any touch for working materials instead of forcing them, I suspect most nylon fin combs will work for you. Especially, if you use a lubricant. D'oh! One reviewer suggested WD-40; I used a silicon spray because it was handy; I suspect a soap such as Simple Green would also do fine. If, however, you expect to just slide one of these down through the fins and all will be well, then forget it, go play some video games instead -- even a metal fin jack won't help you. I ordered both the FRC6 Fin Comb Set and the FPT15 Fin Jack , both by Supco (Sealed Unit Parts Co), because I wanted to be sure to get the job done in one sitting -- and because I was curious as to why nobody was talking about these metal fin jack tools. As it turned out, either one would have done the job... but I'm glad I had both. The nylon fin combs were easier to use, in general, than the fin jack (but, perhaps, only 20% easier). The fin jack, however, was much easier and faster to use on severely bent fins, such as what you might get from a baseball hit (perhaps twice as easy). The fin comb can straighten perhaps 2-3 severely bent fins at a time, whereas the fin jack can do 4-5 at a time in addition to doing it quicker. The FCR6 Fin Comb Set comes with sizes from 8 to 20, skipping 19, paired like so: 8&10, 9&15, 11&13, 12&14, 16&17, 18&20. I gave the set four stars because the teeth on the 14 comb were bent enough to be frustrating if I had needed it. The FPT15 Fin Jack indicates it is good for 14, 15 & 16 fins per inch. Mine actually matched up with the 16 comb and not the 15 comb. Close enough. My York AC unit has fins ranging between 15 and 18 per inch depending on which side and area. 15-16 was nominal. Anyhow, the FPT15 worked fine on all areas including the areas with 18 fins per inch -- many fins just spring back into place when you use next to the right size comb. Still, when I felt like being a perfectionist, I would then redo areas I just used the fin jack on with the right size nylon comb (namely, the 18 comb). According to the packaging, Supco also has FPT10 and FPT13 fin jacks, good for 9-10 and 11-13 fins per inch, respectively. Other hints: If you have any fins severely mangled with a complex bend, expect to do some preliminary work with a pocket knife before combing. I needed to do this only a couple times and the fin jack got everything else just fine. Straighten severely bent fins by starting from the back side of the bend so that you pull them out and away from the rest of the bent fins. Always overlap with straight fins in this case -- don't use all the teeth to try to straighten fins. The nylon combs worked best with a lot of wiggling to work the teeth through the wavy fins. The fin jack goes in too deep to be wiggled side to side. The results won't be perfect (corrected fins won't be perfectly straight or wavy) but they will be good enough to work fine and look decent. Did I mention lubricating yet? Well, do it. I spayed the fins and the tool. This left some greasy spots but those should go away after a few weeks. Try a soap instead if you like and rinse it off, maybe that will work, dunno. I tried spraying just the tools but this did not feel adequate to prevent too much wear.
