DS18 4-GA Marine Grade Tinned 100% Copper OFC Power Wire – 50 Feet is a durable marine conductor designed for boat and vessel electrical systems. With a 4-GA size and a tinned 100% copper OFC core, it delivers reliable power in harsh, salt-tinged environments.
-
Gauge: 4-GA cross-section tuned for power distribution in marine runs
-
Conductor: 100% copper OFC (oxygen-free copper) for high conductivity
-
Tinning: Tinned coating to resist corrosion from salt air and moisture
-
Marine Grade Construction: Built to endure vibration, humidity, and temperature variations
-
Length: 50 Feet
-
Application: Designed as power wire for marine electrical systems
This combination of materials and design helps maintain electrical reliability on watercraft by reducing corrosion risk and ensuring solid conductivity. The 4-GA wire supports power distribution for onboard systems over longer runs, while the tin coating adds an extra layer of protection in salt-prone environments. With 50 feet of routing flexibility, it provides practical versatility for engine bays, cabins, or bulkhead connections.
