Seaguar Brand Image


Fluorocarbon lines were first invented and patented by chemical engineers in Japan, knowing that the attributes of fluorocarbon would be ideally suit to fishing line and that it would revolutionize the industry they applied for a patent and had it granted in 1969. Once quality standards had been established they introduced Seaguar Fluorocarbon Fishing Line in the 1972 Osaka Fishing Tackle Exhibition. Today, they continue to be a world leader in fluorocarbon lines and have continued to develop exclusive resins and extrusion technology, making their offerings of fluorocarbon lines superior to mono-filament, and stronger and more durable than any other fluorocarbons. Seaguar lines also feature Level Wind technology, which offers greater flexibility, increased strength, visual appeal, and smoothly spools onto the reel.

  • Nearly impervious so it maintains its original quality and strength
  • Sinks faster than nylon allowing you to get to the strike zone faster
  • Virtually invisible due to it being closer to the refractive index of water
  • Maintains optimum tensile strength because it absorbs less water than traditional mono-filament lines
  • Maintains knot strength in high-speed hookups and hook-sets
  • Unique double structure creates a combination of higher knot strength and flexibility, and the soft exterior resin enhances knot strength

    Seaguar Fishing Line Anatomy

    FAQ's about Fluorocarbons:

    Can Seaguar fluorocarbon line be used on spinning and bait casting reels?

    Yes, all Seaguar lines are soft enough to be used on any reel for any type of fishing.

    Are all fluorocarbons are created equal?

    No, just because the product says 100% fluorocarbon does not mean it is just like any other on the market. Seaguar is the only brand that makes fluorocarbon lines and leaders from beginning to end without any outside companies involved. Therefore, the difference of quality varies from brand to brand.

    Are all fluorocarbon lines and leaders stiff?

    No, not all fluorocarbons are stiff, in fact Seaguar produces incredibly soft and cast-able lines.

    Do all fluorocarbons have weak knots?

    Although originally knot strength was the weakest part of fluorocarbon, with Seaguar's technology, knot strength is not a factor.

    If fluorocarbon is nicked, will it will shine brightly?

    No, as long as it is 100% fluorocarbon, the refractive index will remain the same and not light up or shine when nicked or scratched.

    Does fluorocarbon become stiff in cold water?

    No, because fluorocarbon absorbs very little water it will remain soft and supple, which makes it perfect for cold water or ice fishing.

    Is it true that fluorocarbon has very little stretch or none at all?

    Fluorocarbon lines and leaders do stretch, but not as much as mono-filaments. Line typically has more stretch than leader, but all Seaguar lines and leaders provide the optimum amount of shock impact and stretch.

    What does double structure mean?

    Double Structure is the combining of two distinct 100% fluorocarbon resins into one solid piece. The exterior resin is soft and contributes to high knot strength, while the interior resin is hard and contributes to higher tensile strength (exclusive to Seaguar).

    What is fluorocarbon made from?

    It is made from hydrogen, carbon, and fluoride, which creates the molecule known as PVDF, or Poly-Vinyl-i-Dene-Fluoride.
