[4:1 High Shrink Ratio for Tight Fit] This 4:1 heat shrink tubing easily slides over connectors, terminals, and irregular wire shapes, then shrinks down to one-quarter of its original diameter for a tight, professional seal, which provides better insulation, stronger hold, and improved waterproof protection, while shrinking quickly without prolonged heating that could damage wires.
[Adhesive Lined Waterproof Seal] The inner wall features marine-grade hot melt adhesive that melts when heated and flows around the connection to create a durable waterproof and oil-resistant seal. This helps protect electrical connections from moisture, corrosion, dirt, and environmental damage, making it perfect for automotive, marine, and outdoor wiring projects.
[Dual Wall Heavy Duty Protection] Polyolefin outer layer for durability and abrasion resistance, adhesive inner lining for airtight waterproof sealing. Double protection, double insurance.
[Continuous Roll – Cut the Length You Need] HUAKAYO heat shrink tubing roll allows you to cut the exact length required for your repair without waste or poor coverage, and makes it easier to handle different wire sizes and repair jobs, saving both time and material.
