Ancor 304602 Adhesive Lined Heat Shrink Tubing 3/8" x 3" Black/Red 2-Pack 12-8 AWG

The Ancor 304602 Adhesive Lined Heat Shrink Tubing provides professional-grade wire termination and protection for marine, automotive, and other demanding electrical applications. This 2-pack includes one black and one red 3-inch tube, each with a 3/8" (9.5mm) diameter that shrinks down to 1/8" (3.2mm) for a secure fit on 12-8 AWG wire.

Key Features:

• Cross-linked polyolefin construction - significantly stronger than PVC tubing and won't burn like PVC alternatives
• Heat-activated adhesive lining - creates an impervious seal against salt water, oil, acids, and sunlight while providing superior strain relief
• 3:1 shrink ratio - highest available shrink ratio provides tight, secure fit by shrinking to 1/3 original diameter
• Activates at 257°F (125°C) - fast, reliable shrinking with standard heat gun
• Wide operating temperature range - rated from -40°C to 110°C for year-round performance
• UL 224 certified - meets recognized safety standards for heat shrink tubing

The adhesive-lined design sets this heat shrink tubing apart from standard versions, providing waterproof protection ideal for marine electrical systems, trailer wiring, and any application where moisture resistance is critical. The dual-color pack with red and black tubes helps with wire identification and organization.
