Seachoice 61521 3-to-1 Heat Shrink Tubing with Adhesive Sealant

The Seachoice 61521 is a marine-grade heat shrink tubing designed for demanding marine and automotive electrical applications. Constructed from flexible polyolefin material, this professional-grade tubing features a 3:1 shrink ratio with an integrated adhesive liner that creates a complete environmental seal when heated.

Key Features:

• Marine-grade flexible polyolefin construction for superior durability
• 3:1 shrink ratio provides versatile sizing options
• Adhesive-lined interior creates watertight, corrosion-resistant seal
• Flame retardant material meets marine safety standards
• Operating temperature range: -55°C to 110°C (-67°F to 230°F)
• Prevents corrosion while enhancing insulation and abrasion resistance

Once installed and heated, the tubing shrinks to conform tightly around wire connections, splices, and terminals while the adhesive liner melts to form a moisture-proof barrier. Ideal for protecting electrical connections in harsh marine environments, this heat shrink tubing provides professional-grade protection against water intrusion, salt spray, UV exposure, and physical wear.
