100% Tinned Copper Butt Connectors for Marine Wiring – #6 AWG
These Ancor Marine Grade™ tinned butt connectors provide a clean, reliable inline splice for #6 AWG wire in marine electrical systems. Made from 100% tinned copper, they resist the corrosion that standard connectors can’t handle in salt air and wet environments. The barrel accepts wire from both ends for a secure crimp connection that maintains conductivity over the long term.
Sold as a 2-pack — enough for a single splice or two separate connections on the same circuit.
Compatible Applications

🔧 Parts Desk Insights
Best use case: This is the go-to connector for a clean, permanent inline splice on #6 AWG wire — a gauge commonly used in shore power feeds, battery charger wiring, bilge pump circuits, and mid-draw accessory runs. The tinned copper barrel is the key advantage over standard connectors in a marine environment; it won’t corrode and lose conductivity over time the way bare copper connectors do. If you need a waterproof or heat-shrink sealed connection, consider the heat shrink butt connector assortment instead. For ring terminal connections on the same gauge, check the Ancor tinned ring terminal range.
