Ancor 12-10 AWG Heat Shrink Butt Connector - 250-Pieces - Jar

The Ancor 12-10 AWG Heat Shrink Butt Connector is a professional-grade electrical terminal solution designed for marine, automotive, and industrial applications where reliable wire-to-wire connections are essential. This bulk 250-piece jar is ideal for technicians, electricians, and DIY installers who need a dependable supply of connectors on hand for multiple projects. Heat shrink butt connectors provide a sealed, insulated joint that protects connections from moisture, corrosion, and mechanical stress—critical requirements in harsh environments.

These connectors are engineered to join 12-10 AWG solid or stranded wire with mechanical and electrical integrity. The heat shrink design features a dual-wall construction: an inner adhesive layer that bonds to the wire insulation and an outer polyolefin shell that provides environmental protection and electrical insulation once heated. Simply insert prepared wire ends into the barrel, crimp using a crimping tool, and apply heat to shrink the outer layer—creating a waterproof, corrosion-resistant connection that meets or exceeds marine and automotive standards. The clear, reusable jar with flip lid ensures easy inventory management and quick identification of the exact connector type needed for your application.

These connectors are compatible with any 12-10 AWG wire gauge application, including marine electrical systems, battery banks, automotive wiring harnesses, and general industrial panel work. Users benefit from the bulk 250-piece count, which minimizes reordering and keeps frequently used terminals accessible in the workshop or truck. Proper crimping and heat application (typically 120–130°C) ensure connections that resist vibration, corrosion, and moisture infiltration—making this product essential for anyone working in salt-spray, high-moisture, or high-vibration environments. Installation requires a compatible crimping tool and a heat source such as a heat gun or shrink tubing applicator.
