Shop butt connectors for boat wiring repairs, wire extensions, and electrical rigging projects. Whether you’re refreshing the wiring on your walleye boat or planning an accessory installation, butt connectors join two wire ends for a tidy inline connection.

Match each connector to your wire gauge and check the product details for insulation, material, and sealing specifications. For boat wiring exposed to moisture, choose connectors suited to the installation environment and follow the manufacturer’s crimping and sealing instructions.
