Stock your wiring kit with Ancor's trusted adhesive-lined heat shrink ring terminals in the popular 12–10 AWG, 3/8" stud configuration.

Key Features
- Ancor Marine-Grade Quality — Ancor is the industry standard for marine electrical terminals; manufactured to meet ABYC E-11 and UL 1426 requirements for marine wiring
- Dual-Wall Adhesive-Lined Heat Shrink — Inner adhesive flows into the crimp zone during heating, creating a fully sealed, moisture-proof connection that resists corrosion in salt and bilge environments
- 12–10 AWG Wire Range — Mid-to-heavy gauge coverage for navigation lights, bilge pumps, VHF radio feeds, windlass controls, and accessory circuits with moderate current demand
- 3/8" Stud Size — Fits the 3/8" studs on battery terminals, main bus bars, and high-current distribution blocks
- Tinned Copper Barrel — Corrosion-resistant tinned copper ensures a low-resistance, gas-tight crimp with long-term conductivity in marine environments
- Closed-Ring Design — Ring cannot back off the stud under vibration, ensuring a permanent, secure connection
- Bulk Pricing — Sold individually at bulk rate; ideal for stocking up for larger projects or professional use

Installation Notes
Strip wire to the correct length so the conductor fills the barrel without protruding. Use a ratcheting crimper rated for 12–10 AWG — do not use plier-style crimpers. Apply heat evenly with a heat gun until the sleeve shrinks uniformly and adhesive flows from both ends. Allow to cool before torquing the stud nut. Do not use an open flame.
Ancor's heat shrink ring terminals are the benchmark for marine electrical terminations — the anc-312625bulk brings that reliability to bulk buyers and professional installers.
