Ancor 16-14 Heatshrink Butt Connectors - 100-Pack

The Ancor 16-14 Heatshrink Butt Connectors - 100-Pack (SKU: CW42087) is the marine electrician's answer to reliable, weatherproof wire termination. After decades on the water, any experienced boater knows that moisture and corrosion are constant enemies of electrical systems. These butt connectors solve that problem by providing a sealed, protected joint that keeps saltwater spray and humidity from compromising your connections. Whether you're rewiring a console, installing new electronics, or repairing existing harnesses, this 100-pack gives you the coverage to handle multiple projects without running short.

What sets these connectors apart is the cross-linked polyolefin tubing construction, which outperforms standard PVC in both durability and safety. Unlike PVC, this material resists cracking, UV degradation, and fire risk—critical when working in confined engine compartments or near fuel systems. The heat-activated adhesive lining creates an impervious seal around the wire joint, preventing water ingress and oxidation that would otherwise lead to voltage drop or complete circuit failure. Designed for 16 to 14 AWG wire gauges, they're ideal for running house batteries, trim systems, lighting circuits, and other mid-amperage boat applications where reliability is non-negotiable.

Professional installers and DIY boaters alike depend on these connectors for bilge pump wiring, navigation light upgrades, and battery management system builds. Installation is straightforward: strip both wires, insert into the connector barrel, and apply heat with a soldering iron or heat gun to activate the adhesive seal and shrink the tubing. The 100-piece count ensures you have spares for future repairs and modifications, eliminating last-minute trips to the chandlery. From center consoles to sailboats to commercial fishing vessels, Ancor heatshrink butt connectors have earned their reputation as the go-to choice for marine electrical work that lasts.
