Ancor 16-14 Gauge - 3/8" Heat Shrink Ring Terminal - 25-Pack

The Ancor 16–14 Gauge 3/8" Heat Shrink Ring Terminal 25-Pack (MPN 311625) is a marine-grade electrical connector engineered for permanent, waterproof connections in saltwater environments. Each ring terminal combines a nylon insulator with cross-linked polyolefin heat-shrink tubing that seals and protects the connection against salt spray, oil, acids, and UV degradation—critical safeguards for any boater wiring electrical systems, batteries, or marine electronics where corrosion and moisture pose constant threats.

The 16–14 gauge wire range accommodates the most common marine battery and accessory circuits, while the 3/8" screw size matches standard battery posts, ground lugs, and panel-mounted hardware found aboard center consoles, offshore sportfishers, and cruising sailboats. The heat-activated adhesive lining inside the shrink tubing bonds to the wire insulation and terminal barrel, creating an impervious seal and strain relief that prevents water intrusion and mechanical failure even under constant vibration and flexing. Cross-linked polyolefin outperforms PVC tubing in marine service—it resists embrittlement from UV exposure and will not burn or release toxic fumes if accidentally exposed to heat during installation or engine-room conditions.

Weekend anglers upgrading trolling motor wiring, adding fish finders, or installing auxiliary battery banks rely on these terminals to eliminate corrosion at connection points. Serious offshore operators and commercial fishing crews use them throughout rigging to ensure every terminal withstands high-amperage loads, repeated on-off cycles, and unforgiving salt-air exposure. The 25-pack quantity suits both small repair jobs and comprehensive system overhauls, making it a standard stock item for marine electricians and boat owners who maintain their own electrical systems.
