Ancor 22-18 AWG Heat Shrink Butt Connector - 250-Pieces - Jar

The Ancor 22-18 AWG Heat Shrink Butt Connector—250 pieces per jar—is a marine-grade electrical terminal solution engineered for reliable connections in saltwater and freshwater environments. These connectors feature dual-wall heat shrink insulation that seals and waterproofs each connection, preventing corrosion that can degrade electrical systems on boats, fishing vessels, and offshore platforms. The 22-18 AWG rating handles moderate-gauge wire applications common in navigation systems, fish finder wiring, bilge pump circuits, and auxiliary lighting installations.

Each connector uses butt-join construction, meaning two wire ends insert into opposite sides of the terminal and crimp simultaneously—eliminating weak single-wire connections. The heat shrink layer activates when exposed to moderate heat, creating a permanent seal around the crimp point that resists moisture intrusion and mechanical vibration failure. This dual-wall design is the marine industry standard for systems requiring UL certification or meeting ABYC (American Boat and Yacht Council) electrical standards. The clear reusable jar includes a flip lid for convenient storage and quick identification of remaining inventory on deck or in the engine compartment.

Serious boaters, charter captains, and offshore anglers rely on these connectors for rewiring fish finder transducers, upgrading bilge and pump systems, installing new VHF antenna coax, or repairing corroded starter and battery cables. Freshwater cruisers use them for GPS and sounder repairs. Commercial fishing vessels stock them as standard spares for emergency repairs at sea. The 250-count jar ensures adequate supply for a full rewiring project or year-round maintenance without running short mid-job. Quality marine electrical work depends on eliminating voltage drop and connection resistance—these heat shrink terminals deliver both, protecting expensive electronics and critical safety systems from the corrosive environment boats face daily.
