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

The Ancor 312403 heat shrink ring terminals provide professional-grade marine electrical connections with superior environmental protection. Designed for 12-10 AWG wire with a 1/4" stud size, these terminals feature heat-activated adhesive lining that creates a waterproof seal when heated, protecting connections from salt water, oil, acids, and sunlight.

Key Features:

  • Heat-Activated Seal: Built-in adhesive lining shrinks to form an impervious, watertight seal at 257°F (125°C)
  • Cross-Linked Polyolefin Tubing: Superior strength compared to PVC, will not burn, and offers the highest shrink ratio (shrinks to 1/3 original size)
  • Marine-Grade Nylon Insulator: Exceptional resistance to sunlight, water, oil, chemicals, vibration, and cut-through damage
  • Pure Tinned Copper Construction: Provides maximum current flow and corrosion resistance for marine environments
  • Brazed Seam: Ensures maximum terminal strength and durability
  • UL Listed and CSA Recognized: Meets stringent safety and performance standards

Specifications:

  • Wire Gauge: 12-10 AWG
  • Stud Size: 1/4"
  • Quantity: 3 terminals per pack
  • Operating Temperature: -40°C to 110°C
  • Shrink Temperature: 257°F (125°C)

These heat shrink ring terminals provide superior strain relief and vibration resistance, making them ideal for demanding marine, RV, and automotive applications where reliable, weatherproof connections are essential.

Quick Ship. Thanks. Low Prices.

Great prices, reasonable charges for expedited shipping

Great prices!!

Best prices with fast shipping and order updates. Will buy from again.<br>

seems great so far exactly what I ordered for a SBF 427 price was great

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Good so far

Excellent service and communication.

Prompt shipment, I got everything under 5 days even if part of my order was drop shipped (in stock items arrived in 2 days). Good communication, would do business again in a heartbeat.
