Ancor 22-18 Gauge - 5/16" Heat Shrink Ring Terminal - 3-Pack

The Ancor 22-18 Gauge - 5/16" Heat Shrink Ring Terminal - 3-Pack is an essential electrical connection component for marine wiring projects. Whether you're upgrading your boat's electrical system, installing new accessories, or repairing existing circuits, these ring terminals provide secure, weatherproof connections that stand up to saltwater and freshwater environments. Anglers and boaters rely on quality terminals to ensure reliable power delivery to navigation lights, fish finders, trolling motors, and battery banks—components that directly impact safety and functionality on the water.

What sets these terminals apart is their cross-linked polyolefin heat shrink tubing, which is significantly more durable than standard PVC and won't burn or degrade under heat or UV exposure. The 22-18 gauge wire compatibility handles mid-range electrical loads common in marine applications, while the 5/16" screw size fits standard battery posts and terminal blocks found on most marine equipment. Heat activation creates a permanent, corrosion-resistant seal around the wire connection, preventing moisture intrusion and oxidation—critical in the harsh marine environment where salt spray and humidity accelerate electrical failure. The 3-pack quantity makes this an ideal supply for a complete project or maintenance kit.

Serious anglers, cruisers, and commercial boat operators benefit most from stocking these terminals on board. Installation is straightforward: crimp the terminal to your prepared wire using a crimping tool, then apply heat with a heat gun or lighter to shrink the tubing and seal the connection. Compatible with both 12V and 24V marine electrical systems, these terminals work with battery interconnects, accessory wiring, and distribution panel connections. Ancor is the trusted standard for marine-grade electrical components, and this 3-pack ensures you have quality spares for maintenance or emergency repairs while underway.
