Ancor Purple 18 AWG Tinned Copper Wire - 100'

Ancor Purple 18 AWG Tinned Copper Wire in 100-foot spools is the marine-grade electrical solution engineered for reliability in saltwater environments where standard wiring fails. Built to exceed UL 1426, ABYC, and U.S. Coast Guard CFR Title 46 standards, this wire delivers the corrosion resistance and durability that serious boaters and fishing enthusiasts depend on for both new installations and repair work.

The 18 AWG tinned copper conductor combines pure copper construction with a protective tin coating, preventing oxidation and galvanic corrosion that corrodes bare or nickel-plated wire in salt air and spray. Premium vinyl insulation rated at 600V and 105°C in dry conditions (75°C when wet) remains flexible in extreme cold down to -40°F, eliminating brittleness at sea. The robust insulation resists salt water, battery acid, petroleum products, UV radiation, abrasion, and heat—critical performance factors on deck or in engine compartments where exposure is constant.

This wire size handles low-voltage DC circuits common in recreational and commercial marine electrical systems: navigation lighting, bilge pump wiring, radio antenna connections, and auxiliary equipment runs. The 100-foot spool length covers most single-circuit installations or repair jobs without excess waste. Whether upgrading a center console fishing boat, installing new electronics on a sailboat, or maintaining chartered vessels, Ancor tinned copper wire provides the material quality that prevents mid-season electrical failures in harsh marine conditions.

Marine electrical codes and insurance standards often require tinned copper wire for new installations because it outperforms cheaper alternatives in salt environments. The purple insulation color follows industry-standard wiring conventions, making circuit identification easier during installation and future troubleshooting.
