Manufacturer

Ancor

<p>For over 40 years, Ancor has been the industry leader for high-quality tinned copper Marine Grade® wire and cable. Founded with a singular mission to deliver electrical products capable of withstanding the harshest marine environments, Ancor has become the gold standard for boat builders, marine electricians, and automotive enthusiasts who demand uncompromising reliability in challenging conditions.</p><h3>Engineering Excellence for Extreme Environments</h3><p>What sets Ancor apart is their commitment to exceeding industry standards. Ancor Marine Grade™ wire and cable is manufactured from tinned copper stranding for maximum protection against corrosion and electrolysis. This electroplating process coats every individual strand with tin, preventing the corrosion that can compromise standard bare copper wire. The result is electrical wire that delivers consistent performance even when exposed to saltwater, battery acid, oil, and UV radiation.</p><p>The company's <a href="/7231-ancor-primary-wire-10128">primary wire</a> offerings showcase this engineering philosophy. 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. The brand's reputation rests on delivering consistent quality across every product category, ensuring that whether you're purchasing 100 feet of wire or a single connector, you're getting the same commitment to excellence that has defined Ancor for more than four decades.</p>

Product Details

The Ancor 311603 Marine Grade Heat Shrink Ring Terminals provide professional-grade electrical connections designed specifically for harsh marine environments. These premium terminals combine a tinned copper ring connector with dual-wall heat shrink tubing featuring an integrated adhesive lining that creates a completely waterproof seal when heated.

Key Specifications:

  • Wire gauge range: 16-14 AWG
  • Fastener size: 3/8" stud
  • Package quantity: 3 terminals
  • Color: Blue for easy wire gauge identification
  • Shrink ratio: 3:1 (shrinks to 1/3 original size)
  • Shrink activation temperature: 257°F (125°C)
  • Operating temperature range: -40°C to 110°C

Premium Marine-Grade Construction:

  • Cross-linked polyolefin heat shrink tubing is significantly stronger and more durable than standard PVC
  • Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and UV exposure
  • Nylon insulator provides superior resistance to sunlight, moisture, chemicals, vibration, and abrasion
  • Tinned copper construction prevents corrosion in marine environments
  • Pure copper conductor ensures maximum current flow and minimal voltage drop
  • Brazed seam construction delivers superior mechanical strength
  • Provides excellent strain relief to prevent wire pullout

Certifications: UL Listed and CSA Recognized for quality and safety compliance.

These heat shrink ring terminals are ideal for marine electrical systems, boat wiring, PWC applications, and any environment where connections are exposed to moisture, salt spray, or vibration. Simply crimp the terminal to the stripped wire, then apply heat with a heat gun to shrink the tubing and activate the adhesive for a permanent, waterproof connection.
