Supco FCR6 フィンコームリング

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.

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’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!!

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.
