Ancor 22-18 Heatshrink Butt Connectors - 500-Pack

The Ancor 22-18 Heatshrink Butt Connectors in this 500-pack represent the workhorse solution for marine electrical installations and repairs on boats of all sizes. Whether you're upgrading wiring in the engine compartment, running new circuits to cabin electronics, or repairing existing connections, these connectors deliver the reliability that serious anglers and boaters depend on when they're far from shore. A 500-piece bulk pack ensures you'll have plenty on hand for major rewiring projects or to stock your boat's maintenance locker without running short mid-job.

Built from cross-linked polyolefin tubing rather than conventional PVC, these 22-18 gauge connectors offer superior durability and heat resistance in the harsh marine environment. The heat-activated adhesive lining creates an impervious, waterproof seal that won't crack or degrade from salt spray, UV exposure, or constant temperature cycling—critical for connections hidden in bilges or exposed to engine heat. When you apply heat with a shrink gun or lighter, the tubing contracts tightly around the wire splice while the inner adhesive melts and flows, creating a permanent bond that resists corrosion and moisture intrusion far better than traditional crimp or solder joints alone.

Anglers running trolling motors, fish finders, GPS systems, and cabin lighting will find these connectors indispensable for connecting 22-18 AWG wire pairs without soldering or complicated tools. They work equally well for stereo wiring, bilge pump circuits, and through-hull fitting connections where moisture and vibration would compromise inferior connections. Keep this 500-pack in your shop or aboard your vessel—the combination of bulk quantity, proven construction, and marine-grade materials makes it the economical choice for serious boat owners who maintain their own electrical systems.
