Ancor 302148 Adhesive Lined Heat Shrink Tubing 3/16" x 48" Black

Ancor's adhesive-lined heat shrink tubing provides professional-grade electrical insulation and waterproof sealing for marine, automotive, and industrial wiring applications. This 48-inch black tube features a 3/16" diameter that shrinks down to 1/16" for a secure, tight fit on wire gauges 20-12 AWG.

Key Features:

• Cross-linked polyolefin construction - significantly stronger and more durable than standard PVC tubing with superior fire resistance
• Heat-activated adhesive inner lining creates an impervious seal against salt water, oil, acids, and UV sunlight exposure
• 3:1 shrink ratio - industry's highest shrink ratio ensures tight, secure fit and excellent strain relief
• Activates at 257°F (125°C) for reliable heat shrinking
• Wide operating temperature range from -40°C to 110°C (-40°F to 230°F)
• UL 224 certified for electrical safety and performance

This single 48-inch section provides flexibility for custom-length applications in boat wiring, trailer connections, automotive repairs, and other harsh-environment electrical installations. The adhesive lining flows when heated to completely encapsulate and seal wire connections, preventing corrosion and ensuring long-lasting reliability.
