P-Line CXX-Xtra Strong 1/4 Size Fishing Spool

B · Low PFAS

Lower PFAS concern; fishing line is a commodity material with no known water-repellent coating or specialty coatings.

Verdict: BuyMonofilament nylon fishing line with no known coatings or additives; lower PFAS concern and no established other hazards for this commodity material.

P-Line CXX fishing spools are standard monofilament nylon, a basic thermoplastic with no inherent reason to contain PFAS. The brand makes no PFAS claims and no public lab data exists. Fishing line is not treated with water-repellent or grease-resistant finishes typical of PFAS-risk products.

The full breakdown

What it's made of and why it matters

P-Line CXX-Xtra Strong is extruded monofilament nylon (likely nylon 6 or 6.6), a thermoplastic polymer with no known Teflon-family coating coatings, water-repellent finishes, or specialized additives beyond standard UV stabilizers and colorants. The material is chemically inert in freshwater and saltwater under normal fishing conditions. This is a commodity product with minimal processing variation across brands in this category.

The brand's record and disclosure

P-Line is a subsidiary of Pure Fishing, a large recreational fishing equipment manufacturer. The brand maintains no public PFAS disclosures or certifications for this product line. No recalls or safety controversies specific to P-Line monofilament are on record. The company does not publish material safety data sheets for consumer fishing line, which is typical for the category.

How it compares in its category

Monofilament fishing line is chemically similar across reputable brands; P-Line CXX is mid-range in the commodity market with no material distinctions in hazard profile versus Berkley, Stren, or other major brands. Braided and fluorocarbon alternatives carry different chemical profiles (polyethylene and polyvinylidene fluoride respectively), but monofilament nylon remains the baseline choice. No brand has demonstrated superior or inferior safety data for this material class.

If you buy it

Store spools in a cool, dry place away from direct sunlight to slow UV degradation of the nylon polymer; nylon becomes brittle over 2-3 years of storage. Do not expose to solvents or high temperatures above 80C. Replace line annually or after visible cracking, discoloration, or loss of strength. This product is intended for single use (casting and retrieval); do not reuse degraded line, as breakage increases fish entanglement risk.

Beyond PFAS: other things we checked

Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”

Possible

UV and thermal degradation of nylon polymer

Nylon monofilament degrades under prolonged UV exposure and elevated temperatures, becoming brittle and prone to breakage. This affects durability and safety (line failure during use) rather than chemical toxicity, but is inherent to the material class.

None known

Heavy metals in colorant pigments

P-Line CXX uses standard azo dyes and inorganic pigments for color. No lead, cadmium, or chromium contamination has been documented in monofilament fishing line; regulatory oversight is minimal but no incidents are on record for this brand or category.

Possible

Microplastic shedding during use

Friction and abrasion during casting, retrieval, and handling can shed fine nylon particles into aquatic environments. This is a known issue with all monofilament fishing line; P-Line has no documented mitigation measures. Environmental persistence is the primary concern, not human health.

None known

Residual monomers or oligomers in nylon resin

Industrial nylon extrusion may leave trace unreacted caprolactam (nylon 6) or other oligomers in the finished line. No toxicological data suggests hazard from contact with skin or incidental ingestion via food; fishing line is not designed for ingestion and poses choking risk only to very young children.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.

No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.

The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.

Formulations and coatings change between production runs. Always check the current label before buying.
