Ancor Heat Shrink Butt Connector Multi-Pack - 250-Piece - Jar

The Ancor Heat Shrink Butt Connector Multi-Pack—250-Piece—Jar is the marine electrician's go-to solution for reliable, waterproof wire terminations aboard vessels of all sizes. Whether you're rewiring a center console, upgrading navigation systems, or making emergency repairs at sea, these heat shrink connectors ensure corrosion-resistant connections that stand up to saltwater exposure and harsh marine environments. After years on the water, you learn that cheap electrical connections are a liability; Ancor connectors are engineered specifically for boats, where moisture and vibration demand uncompromising quality.

Each connector features dual-wall heat shrink tubing that bonds adhesive to the wire insulation when heated, creating a seal that blocks water ingress and resists corrosion better than soldered joints alone. The 250-piece assortment includes 50 connectors rated for 22–18 AWG wire, 150 for 16–14 AWG (the most common marine gauge), and 50 for 12–10 AWG heavy-duty applications—coverage for virtually every circuit on deck or below. The clear, reusable jar keeps connectors organized and visible, with a flip lid for quick access when you're working against daylight or rough conditions, and the compact 4×4×6-inch package stows easily in a toolbox or marine locker.

Boat owners, marine electricians, and liveaboards benefit most from buying in bulk; the 250-piece count means you won't run dry mid-project or need emergency supply runs before casting off. These connectors work with any marine electrical system—from battery banks and bilge pumps to thruster controls and fish finder installations. Simply insert stripped wire ends, heat with a standard heat gun, and the shrink tubing seals permanently. For anyone serious about maintaining reliable, saltwater-resistant electrics, the Ancor Heat Shrink Butt Connector Multi-Pack is insurance against electrical failure when you're far from shore.
