Phillips Cable 6-302 Heat Shrink Tubing Black 12-10 Gauge 6 Inch Flexible Dual Wall

The Phillips Cable 6-302 is a professional-grade heat shrink tubing designed to provide superior insulation and protection for electrical wiring in automotive, marine, RV, and commercial vehicle applications. Part of the STA-DRY Flexible Dual Wall series, this tubing features an adhesive-lined construction that creates a waterproof seal when heated.

Key Features:

• Fits 12-10 gauge wire applications with 0.37-inch inner diameter
• Adhesive-lined cross-linked polyolefin construction for waterproof sealing
• Flexible design remains pliable in extreme conditions down to -40°F (-40°C)
• Dielectric strength of 700V for reliable electrical insulation
• Black color for professional appearance and polarity identification
• 6-inch length pieces (6 pieces per polybag package)

The dual-wall construction combines a cross-linked polyolefin outer layer with a thermoplastic adhesive inner lining that melts and flows when heated, forming a permanent bond between the tubing and the wire. This creates an environmental seal that protects wire splices and connections from moisture, fluids, and corrosion—critical for harsh outdoor and under-hood applications. Ideal for primary wire repairs, electrical connections, and cable management in trucks, trailers, marine vessels, and heavy equipment.
