KastKing Sharky III Spinning Reel
Fishing reel materials indicate minimal PFAS exposure.
Metal and stainless steel construction with no water repellent treatments typical of PFAS use keeps concern low.

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.
Aluminum corrosion and oxidation
Aluminum spools corrode if saltwater or moisture is not rinsed away; this degrades the reel's function and appearance but does not leach toxic compounds into food or water supplies. Proper maintenance eliminates this risk.
Bearing corrosion and seizing
Stainless steel bearings are corrosion-resistant but not corrosion-proof; saltwater exposure without rinsing can pit and eventually seize ball bearings, rendering the reel unusable. This is a performance failure, not a toxicity hazard.
Drag washer material degradation
Drag washers are typically felt or synthetic polymer; they wear with use and may shed fibers into the reel housing after 1-2 years of regular saltwater fishing. Replacement is routine maintenance and inexpensive; no health hazard occurs from material shedding into water.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No paint, ceramic, or polymer coating on the spool-bearing interface; aluminum and stainless steel do not leach cadmium, lead, or other regulated metals under normal fishing use. No documented cases or manufacturer warnings exist.
Source, FDA ↗Plastic or rubber components off-gassing
The Sharky III spool and main frame are metal; plastic is limited to handle grips and internal gaskets. No volatile organic compound or formaldehyde off-gassing has been reported, and fishing reels do not experience heat cycles that would trigger polymer degradation.
The full breakdown
What it's made of and why it matters
The Sharky III uses an aluminum spool paired with stainless steel ball bearings and machined metal components. Aluminum spools are industry standard for spinning reels because aluminum resists saltwater corrosion better than steel and is lightweight. Stainless steel bearings resist rust and maintain smooth drag function over time. No paint, enamel, coating, or plastic contact surfaces in the drag or bearing system pose typical leaching risks.
The brand's record and disclosure
KastKing is a budget-oriented fishing brand owned by parent company Eposeidon. No public disclosures, certifications (ISO, NSF), or safety controversies appear in established sources for this reel model. The brand does not advertise material testing, heavy metal limits, or environmental compliance; this is typical for consumer fishing equipment but reflects limited transparency. No recalls affecting the Sharky III spinning reel are recorded.
How it compares in its category
Entry-level spinning reels universally use aluminum spools and stainless steel internals; the Sharky III is materially consistent with Shimano, Abu Garcia, and Penn budget lines. The main differentiation among budget reels is bearing count and drag smoothness rather than material safety. KastKing's price point is lower, which typically reflects simpler QC and fewer third-party audits, not inherently worse chemistry or coating hazards.
If you buy it
Rinse the reel with fresh water after each saltwater outing to prevent aluminum oxidation and salt corrosion buildup. Do not submerge the reel or allow water inside the spool housing, as trapped moisture can corrode internal bearings despite stainless steel construction. Inspect the drag washer annually for wear; replacement kits are inexpensive and available from the manufacturer. Store in a dry location; no special lubricants beyond standard reel oil are needed or recommended.
