What KastKing Spinning Reels is made of, ingredients and materials
KastKing spinning reels are constructed primarily from aluminum or graphite composite bodies with polymer (likely nylon or acetal) gears, bail arms, and handle components. The reel body is typically finished with epoxy or polyurethane coatings to resist corrosion in freshwater and saltwater environments. These materials are inherently low-toxicity for hand contact, but coating integrity matters, degraded epoxy or polyurethane can shed microparticles and potentially leach bisphenol compounds or uncrosslinked oligomers if the protective layer fails.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Unknown / proprietary coating
A coating is recorded with no disclosed chemistry.
Coating degradation and metal leaching
Epoxy or polyurethane topcoats on aluminum bodies can crack or peel with age, mechanical wear, or UV exposure, potentially exposing aluminum to saltwater and causing corrosion. Degraded epoxy can also shed microparticles; no data exists for KastKing reel coatings specifically.
Bacterial or organic growth in spool mechanism
If reels are stored damp or left wet, organic biofilm can colonize the spool and bail bearings, creating corrosion pits and potential mold. Not a chemical hazard but a maintenance risk.
PFAS
Some industrial epoxy and polyurethane formulations contain per- or polyfluoroalkyl substances for water and stain resistance. KastKing has not disclosed coating chemistry; PFAS presence cannot be ruled out and is assessed separately (50/100 safety grade).
Source, ATSDR ↗What’s reassuring
Polymer gear and bail arm integrity
Nylon and acetal copolymer gears are chemically stable under normal fishing conditions. No known releases of bisphenol compounds or phthalates from these materials in fishing reels; risk is minimal unless reels are heated (not a typical use case).
Heavy metals
If reel bodies are graphite-filled nylon or epoxy, graphite itself is inert. Some graphite composites may contain trace antimony or cadmium from pigments, but no toxicity pathway exists for hand contact with finished reels.

The brand's record and disclosure
KastKing is a fishing-gear manufacturer owned by Eposeidon Group with a public presence primarily through Amazon and direct e-commerce. The brand has not published material safety data sheets, PFAS testing results, or third-party certifications for reel components. No significant product recalls or safety controversies involving KastKing reels appear in FDA or CPSC records. The brand's silence on material transparency is consistent with many mid-market fishing brands, but limits independent hazard verification.
How it compares in its category
Spinning reels across price tiers (budget to premium) use nearly identical material palettes, aluminum or composite bodies with polymer gears and epoxy topcoats. KastKing reels are competitively positioned and do not stand out as having notably higher PFAS concern than equivalently priced Shimano, Abu Garcia, or Penn models. The main differentiator is coating durability and maintenance sensitivity; mid-range reels of all brands are prone to corrosion if not rinsed and dried after saltwater use.
If you buy it
Rinse the reel thoroughly with fresh water immediately after saltwater exposure to prevent corrosion and coating breakdown, which can expose unfinished metal and polymers. Avoid leaving the reel in direct sunlight for extended periods, as UV exposure can degrade polyurethane coatings over time. Inspect the bail arm, spool, and handle connection annually for cracks, peeling, or pitting; replace or repair if the coating is compromised to slow internal corrosion. Do not submerge reels; hand-wash only with a soft brush.
