Ancor Marine Grade™ wire and cable is manufactured from tinned copper stranding for maximum protection against corrosion and electrolysis.

Ultra flexible (Type 3) stranding resists fatigue due to vibration and flexing. Exceeds all UL 1426, US Coast Guard Charter boat (CFR Title 46) and ABYC standards. Available in multiple gauges and a full spectrum of colors to match proper wiring protocols, these products are essential for anyone building or maintaining electrical systems in demanding applications.</p><h3>Complete Wire Management Solutions</h3><p>Our extensive product line encompasses everything you need for your next wiring project, including wire, cable, terminals, connectors, wire management products, and hand tools. Beyond wire itself, Ancor has developed a comprehensive ecosystem of complementary products. Their <a href="/7231-ancor-wire-tie-17375">wire ties</a> feature UV-resistant construction that won't become brittle in harsh sunlight, while their terminals utilize double-crimp designs for maximum strain relief and connection integrity.</p><p>For vehicle protection needs, Ancor even offers <a href="/7231-ancor-car-cover-1020">car covers</a> engineered to guard against the elements. Meanwhile, specialized components like <a href="/7231-ancor-disc-brake-rotor-1896">disc brake rotors</a> and <a href="/7231-ancor-automatic-transmission-control-solenoid-7752">automatic transmission control solenoids</a> demonstrate the brand's expanding reach into broader automotive applications.</p><h3>Trusted by Professionals, Accessible to All</h3><p>All of our products are built for the harsh marine environment and conform to industry standards. Whether you're rewiring an entire vessel, making repairs to an RV electrical system, or upgrading automotive wiring harnesses, Ancor provides the durability and performance needed for installations that last.

Product Details

The Ancor 321503 Marine Gradeâ„¢ Heat Shrink Ring Terminals provide professional-grade electrical connections designed for harsh marine environments. These terminals feature heat-activated adhesive built into the sleeve that creates a watertight seal when heated, offering superior protection against moisture, salt spray, and corrosion.

Key Features:

  • 8 AWG wire gauge capacity for medium-duty electrical connections
  • 5/16" stud size for secure fastener attachment
  • Dual-wall construction with adhesive-lined heat shrink tubing
  • Creates watertight seal when properly heated
  • Superior vibration and strain relief for marine applications
  • Tinned copper construction resists corrosion
  • Red color-coding for easy wire gauge identification
  • UL Listed and meets military specifications

Simply crimp the terminal to the wire, then apply heat using a heat gun to activate the adhesive and shrink the tubing. The result is a durable, weatherproof connection that outperforms standard ring terminals in demanding marine, automotive, and outdoor applications. Each package includes 3 terminals.
