Seachoice 62621 Marine Heat Shrink Tubing 3/8" x 48" Yellow with Adhesive

Seachoice 62621 is a marine-grade, flexible polyolefin heat shrinkable tubing designed for demanding marine electrical applications. This yellow tubing measures 3/8 inch diameter by 48 inches long and features a dual-wall construction with an adhesive liner for superior environmental protection.

Key Features:

• 3:1 shrink ratio allows versatile sizing for various wire gauges and connections
• Adhesive inner liner creates a complete waterproof seal when heated
• Flame retardant construction meets marine safety standards
• Temperature rated from -55°C to 110°C for extreme marine environments
• Flexible polyolefin material resists cracking and provides excellent abrasion resistance
• Yellow color for easy wire identification and organization

Once heated and installed, this dual-wall heat shrink tubing provides a complete environmental seal that prevents corrosion, enhances electrical insulation, and improves abrasion resistance. The adhesive liner melts during heat application to form a moisture-proof barrier, making it ideal for below-deck wiring, bilge pump connections, and other marine electrical repairs where moisture protection is critical.
