100% Tinned Copper Butt Connectors for Marine Wiring – #2 AWG
These Ancor Marine Grade™ tinned butt connectors provide a clean, reliable inline splice for #2 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 — critical on high-current circuits where a poor connection creates heat and voltage drop.
Sold as a 2-pack — enough for a single splice or two separate connections on the same circuit.
Compatible Applications
- Inline wire splices on #2 AWG marine circuits
- Battery charger and shore power feed wiring repairs
- Windlass and anchor winch circuit connections
- High-draw DC accessory and distribution wiring
- Inverter input cable splices on #2 AWG runs

🔧 Parts Desk Insights
Best use case: This is the right connector for a permanent inline splice on #2 AWG wire — a heavier gauge commonly used in windlass circuits, battery charger feeds, and high-draw DC accessory runs where current capacity matters. At this gauge, connection quality is especially important: a poor crimp creates resistance, heat, and voltage drop that can affect equipment performance and create a fire risk over time. The tinned copper barrel resists corrosion far better than bare copper in a marine environment. If you need a fully waterproof connection, consider the heat shrink butt connector assortment. For even heavier gauge splices, step up to the 1/0 or 2/0 AWG versions in the same family.
