Ancor 22-18 Gauge - 1/4" Heat Shrink Ring Terminal - 100-Pack

The Ancor 22-18 Gauge 1/4" Heat Shrink Ring Terminal 100-Pack is an essential electrical connection component for marine wiring applications where reliability cannot be compromised. Whether you're upgrading your boat's electrical system, installing new navigation equipment, or repairing corroded battery connections, these ring terminals provide the secure, weather-resistant connections that keep your vessel running safely on the water. Built by Ancor, a trusted name in marine-grade electrical components, this 100-pack offers the quantity and quality needed for comprehensive electrical projects on fishing boats, cruisers, and commercial vessels alike.

Each terminal features cross-linked polyolefin heat shrink tubing that vastly outperforms standard PVC alternatives—it won't burn or degrade under the extreme heat generated during high-amperage connections, and it resists salt spray, UV exposure, and diesel fumes that characterize the marine environment. The 1/4" ring terminal accepts standard battery and distribution post bolts, while the 22-18 gauge wire range accommodates the mid-size conductors typical in boat electrical panels, bilge pumps, and auxiliary circuits. When heat is applied during installation, the tubing shrinks tightly around both the crimped barrel and stripped wire, sealing out moisture and preventing oxidation—the primary cause of electrical failures in salt-water boats.

Anglers and boaters who maintain their own electrical systems will appreciate the professional-grade performance of this 100-pack; a single box eliminates repeated supply runs and ensures consistent terminal quality throughout your project. Installation requires a crimping tool rated for heat shrink terminals and a heat source such as a heat gun or lighter to activate the tubing shrink. These terminals are ideal for battery interconnects, ground bus connections, alternator leads, and auxiliary power distribution on boats ranging from small center consoles to larger displacement cruisers where electrical integrity directly impacts safety and performance on the water.
