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 320303 heat shrink step-down connectors provide a professional, watertight solution for joining different gauge wires or connecting multiple wires of the same gauge. This 3-pack of adhesive-lined connectors is ideal for marine, automotive, and powersports applications where moisture and corrosion resistance are critical.

Key Features:

  • 4:1 shrink ratio tubing creates a completely watertight seal between wire connections
  • Adhesive-lined heat shrink provides superior environmental protection compared to standard butt connectors
  • Flared barrel design with uniform copper walls ensures proper mechanical crimping
  • Clear heat shrink tubing allows visual verification of crimp accuracy
  • Crimp indicator mark on barrel guides proper tool placement
  • Color-coded stripes indicate correct crimp die selection
  • Can step down from one wire gauge to another or connect multiple wires of the same gauge
  • Sealed alternative to quick-tap or 3-way connectors in corrosive environments

Designed for 12-10 AWG wire applications, these connectors combine the convenience of heat shrink technology with the reliability of proper crimped connections. Simply crimp the wire into the appropriate barrel end, then apply heat to shrink and seal.

WarningWARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.
