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.

Product Details

Ancor Marine Grade Adhesive Lined Heat Shrink Tubing provides professional-grade wire protection and sealing for marine electrical connections. This 3-pack includes three 3-inch long sections of 3/4-inch diameter tubing that shrinks down to 1/4-inch, suitable for 8-2/0 AWG wire.

Key Features:

  • Cross-linked polyolefin construction - significantly stronger than PVC and won't burn like PVC tubing
  • Heat-activated adhesive lining - creates an impervious seal against salt water, oil, acids, and UV sunlight while providing excellent strain relief
  • Superior 3:1 shrink ratio - shrinks to 1/3 of original diameter for tight, secure fit
  • Wide temperature range - operates from -40°C to 110°C (-40°F to 230°F)
  • UL 224 listed for quality and safety assurance

Specifications:

  • Diameter: 3/4" (19mm) before shrinking, 1/4" (6.4mm) after shrinking
  • Length: 3" (7.6cm) per piece
  • Wire range: 8-2/0 AWG
  • Shrink activation temperature: 257°F (125°C)
  • Color: Black
  • Quantity: 3 pieces per package

Ideal for marine, automotive, and outdoor electrical applications where maximum protection against harsh environments is required. The adhesive lining melts and flows when heated, creating a waterproof seal that protects connections from corrosion and mechanical stress.
