Ancor 304148 Adhesive Lined Heat Shrink Tubing 3/8" x 48" Black 12-8 AWG

The Ancor 304148 adhesive-lined heat shrink tubing provides professional-grade wire sealing and protection for marine, automotive, and other demanding electrical applications. This 48-inch section of 3/8-inch diameter tubing shrinks down to 1/8-inch for a secure, watertight fit on 12-8 AWG wire.

Key Features:

• Cross-linked polyolefin construction - significantly stronger and more durable than standard PVC tubing and will not burn like PVC
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and sunlight while providing strain relief
• Superior 3:1 shrink ratio - shrinks to one-third of original diameter for maximum coverage range
• Activates at 257°F (125°C) with standard heat gun
• Wide operating temperature range: -40°C to 110°C (-40°F to 230°F)
• UL 224 Listed for quality and safety compliance

Specifications:

• Length: 48 inches (122 cm)
• Diameter (before shrinking): 3/8 inch (9.5 mm)
• Diameter (after shrinking): 1/8 inch (3.2 mm)
• Wire range: 12-8 AWG
• Package quantity: 1 piece
• Color: Black

Ideal for marine wiring, trailer connections, and any application requiring superior moisture protection and environmental resistance. The adhesive lining melts when heated to form a watertight seal that prevents corrosion and extends the life of electrical connections.
