Pacer Performance BHW3/4-3BKRD Heavy Wall Heat Shrink Tubing 3/4" x 3" Black/Red 2-Pack

Pacer Performance Heavy Wall Heat Shrink Tubing provides professional-grade protection for battery cable connections and electrical splices in automotive, marine, and powersports applications. This combo pack includes two 3/4-inch diameter by 3-inch long pieces—one black and one red—for organized positive and negative terminal identification.

The heavy wall construction features a dual-purpose thermoplastic adhesive liner that flows and encapsulates connections when heated, creating a waterproof seal. Once cooled, the tubing provides the mechanical strength of a superior adhesive combined with the corrosion protection of high-quality mastic, making it ideal for harsh environmental conditions including direct burial and submersible applications.

Key Features:

• Heavy wall design with excellent insulating, abrasion-resistance, and strain-relieving properties
• Internal thermoplastic adhesive liner creates waterproof seal and environmental barrier
• Shrinks when heated above 248°F (120°C) for easy installation
• Highly abrasion and impact-resistant construction
• Adheres to PVC, neoprene, polyolefin, EPR, steel, and aluminum surfaces
• Excellent resistance to acids, alkalis, fuel, oil, and solvents
• Adhesive lining provides superior protection against moisture and contaminants

Applications:

• Battery cable termination and protection
