Ancor Marine Grade™ 311525 heat shrink ring terminals are built for reliable, corrosion-resistant marine electrical connections. The heat-activated adhesive-lined shrink sleeve helps form a tight seal for protection against moisture and helps reduce vibration and strain at the wire-to-terminal connection.

Key Features

  • Tinned copper construction for corrosion resistance and good conductivity
  • Adhesive-lined heat shrink sleeve shrinks to form a tight seal
  • Designed to help provide vibration and strain relief after crimping and heating
  • Marine grade 25-pack for projects, spares, and repairs

Intended Use

  • Marine wiring and electrical connections
  • Boat and RV accessory wiring where sealed ring terminals are required
  • Replacement and repair of ring-terminal connections in harsh, moisture-prone environments

Parts Desk Insights

Best Use Case: Use these adhesive-lined heat shrink ring terminals when you want a sealed, vibration-resistant ring terminal connection for 16–14 AWG marine wiring—especially in areas exposed to moisture, salt, or spray.

Common Issues: For best results, make sure the crimp is sized correctly for the 16–14 AWG range and that you fully heat the sleeve so the adhesive activates and seals around both the wire and terminal barrel. If the sleeve isn’t fully shrunk, the seal may be incomplete.
