4awg Butt Connector (25)

These 4 AWG butt connectors deliver reliable wire terminations for mid-range marine electrical circuits. Built to withstand saltwater exposure, they maintain excellent conductivity and corrosion resistance in challenging marine environments. For professional-grade results, use an Ancor lug crimper to achieve proper contact pressure and ensure secure, load-bearing connections. Waterproof each splice by applying Ancor adhesive-lined heat shrink tubing over the connection, creating a protective barrier against moisture, salt spray, and oxidation. The 25-pack provides sufficient connectors for system repairs, component upgrades, or moderate rewiring projects on recreational and commercial vessels.
