If you search for the best Fluorocarbon Fishing Line, you will probably come up with names like Seaguar and Berkley. But nowadays, we have quite a few newcomers to the market that are making a splash.
Companies like Kastking and P-Line might be new to the market, but they are making some quality products and giving the big names a run for their money.
Now, don’t get me wrong, Seaguar and Berkley still produce great lines. That’s why I’m still including them in my Top 5. But they aren’t the only (and maybe not even the best) ones on the market at the moment.
Before we get into my list, I would like to answer a few questions I keep getting asked about Fluorocarbon Line.
What is Fluorocarbon Fishing Line?
The fluorocarbon line was invented in Japan back in 1971 by the Kureha Company. To put it simply, it’s a combination of elements: Hydrogen, Carbon, and Fluoride.
Fluorocarbon goes through a process called extrusion, allowing it to become a single strand of line, similar to nylon monofilament, but much more durable. Fluorocarbon molecules are tightly packed together making the fishing line much denser and heavier.
Is it Better than Monofilament?
The short answer is yes. The long answer would take way too long to answer here. That being said if you would like to learn more about Fluorocarbon, and all the benifits, follow this link to:
The benefits of fluro over mono are numerous and well worth your time to learn about before making your next fishing line purchase.
Most Fluorocarbon lines boast similar characteristics (check out the link above to find out more) so I won’t keep repeating myself. Instead, I will highlight what sets each different line apart from the others, and what makes it better (or worse)
So Let’s dive in and see what’s best on the market at the moment and how they compare to each other.
KastKing Kovert is a 100% pure fluorocarbon fishing line engineered and manufactured in Germany. Kovert Fluorocarbon Line delivers exceptional performance when you need a sensitive, shock-resistant, ultra-low visibility clear fishing line or fluorocarbon leader for tough conditions.
- Strength 4 – 50 LB
- Length 50 – 200 Yards
- Diameter .006 – .028 Inch or .152 – .711mm
- Material 100% Fluorocarbon
- Color Clear
KastKings Kovert has one of the smallest diameters compared to most other fluorocarbon lines on the market. This means more lines on the spool. Another thing that sets this line apart from some of the competitors is that it’s 100% fluorocarbon, whereas others may only be coated.
The best thing about the KastKing Kovert Fluorocarbon fishing line and fluorocarbon leader is its knot strength. It has an extremely strong knot and has higher elasticity, and can dump fish faster than most other fluorocarbon fishing lines in the industry. Its special material also reduces the fluorocarbon fishing line’s shininess.
Rating 8.5 / 10
Berkley is one of those names that come straight to mind when you think of a fishing line. They have been around for a long time, and their fishing line has come a long way. Berkley Vanish came along around fifteen years ago. Over that time they have been improving until now, and you have one of the best fluorocarbon lines around.
- Strength 4 – 100 LB
- Length 20 – 2000 Yards
- Diameter .007 – .040 inch or .25 – 1.04mm
- Material 100% fluorocarbon
- Color Clear/Red/Gold
- Transition Technology
Again, like the KastKing, you can get this line in both leader and main. But Berkley Vanish has something a bit different, Transition Line. You can choose between red and gold in these transition lines. It remains clear and invisible underwater, but above, the line retains its color so you can see it.
The superior abrasive resistance makes it one of the stronger lines on this list, though it doesn’t boast the best knot strength. Because of this, I couldn’t mark this line as high as I would like, but I still believe it is maybe the best on the market, especially with the added benefits of the Transition line.
Rating 9 / 10
Seaguar is a big name in the Fluorocarbon Fishing line, and for good reason. This German-made product has been at the top for a long (long) time. This line is primarily used in freshwater fishing, though can be used in salt too. The InvizX is only available on the mainline as the max strength is only 25 LB. Here are some of the specifications;
- Strength 4 – 25 LB
- Length 200 – 1000 yards
- Diameter .007 – .017 inch or .165 – .435mm
- Material 100% fluorocarbon
- Color Clear
A soft, supple, and more castable line, Seaguar InvizX can be used in both Spinning Reels and Bait Casting Reels. The strong yet sensitive line offers advanced hook-setting power and knot strength. Suitable for both fresh water and saltwater.
It has much less stretch than many other fluorocarbons, has great castability, virtually no memory, and is reasonably priced for a premium line. The only real downfall with this line is that 25 LB is the max you can get. This is why it is recommended more for freshwater.
8.5 / 10
This fluorocarbon line is not 100% made of one component but combines fluorocarbon technology and copolymer features. P-Line Floroclear may not be 100% pure fluorocarbon, but it’s still waterproof and has a really low water absorption.
This is how they keep their small diameter which is as much as 30% thinner than other lines of similar pound tests. Some key things to keep in mind are;
- Strength 4 – 30 LB
- Length 260 – 300 yards
- Diameter .007 – .02 inch or .18 – .51mm
- Material Fluorocarbon coating
- Color Clear/ Green Mist
This thinner diameter brings a much greater distance of casting, knot strength, and durability. P-Line Floroclear is much softer than some other brands, giving it a nicer feel when casting and retrieving. One advantage of only having the fluorocarbon coating is the cost.
Though it may cost more than mono, it’s quite a bit cheaper than some of the leading 100% fluorocarbon lines around.
To finish off the list, we have another product from Seaguar. This is another line that you can get as either main or leader.
Seaguar Red Label can work as your main fishing line but it has a bit too much memory (has coils from the packaging) which can cause tangles. For this reason, it may be better for a leader.
- Strength 4 – 20 LB
- Length 175 – 250 yards
- Diameter .006 – .016 inch or .165 – .405mm
- Material 100% Fluorocarbon
- Color Clear

Seaguar Red Label is also UV-resistant, chemical-resistant, nonabsorbent, high-density, and impervious to cold conditions. Made from 100% Seaguar resins and produced using our proprietary extrusion process. This line seems like the go-to, but unfortunately, it falls short on two very key things. The knot strength, and abrasive resistance.
Depending on where and what you are fishing for, abrasiveness may or may not be a factor. Because of this, I haven’t let it affect the score, but the knot strength is a big one, and here it doesn’t hold up to the others on this list, which is disappointing.
That’s A Wrap
My choice for the best available for a price, abrasive capabilities, knot strength, and strength would have to be The Berkley Vanish. I know what you’re thinking “you said it doesn’t have good knot strength”. The truth is, it has really good knot strength, just maybe not the best. And with the added benefit of the Transition Line, it becomes the best all-around for my books and is well worth the money.
Well, there you have it. The five best Fluorocarbon Fishing lines are on the market at the moment. Of course, with the advancement in technology, fluorocarbon is just getting better and better. So watch this space for any new line coming out.

You may have noticed I haven’t included any straight-out leader line in this post. I wanted to concentrate on the mainline at this point. For that, I suggest you head over to my post
I hope you enjoyed reading this post, and that I might have helped you decide what is the best choice for you. I would love to hear any feedback you might have. So if you have any questions or comments, please leave them in the comment section below. As Always
