Tired of short tubes that leave wires exposed? Frustrated with kits packed with tiny, useless filler sizes? Or storage boxes that don’t properly fit heat shrink tubing? ALEKOR delivers professional-grade quality designed for real wiring work.
WHY LENGTH MATTERS
Every tube is 50mm (2”) long—longer than standard kits. It ensures full overlap on terminals and tight bends, delivering better strain relief with no exposed wire.
PRO-SELECTED SIZES — ZERO WASTE
7 essential diameters from 1/8” to 5/8”. No tiny, unusable fillers. All 240 pieces are practical for real electrical work.
PREMIUM STORAGE CASE
Durable, stackable, and jobsite-ready. The solid rectangular case (6.5” × 4.8” × 2.3”) is easy to store, stack, and carry while keeping every tube neatly organized and protected during transport and use.
Dual Wall Construction Creates a True Waterproof Barrier
Outer polyolefin provides insulation.
Inner adhesive liner melts and flows when heated, sealing out moisture, saltwater, and corrosion for long-term reliability.
Professional dual-wall heat shrink tubing that creates a waterproof, corrosion-proof seal for automotive, marine, engine bays, wiring harnesses and electrical repairs.
3:1 SHRINK RATIO
Heavy-duty dual-wall tubing with a heat-activated adhesive liner. When heated, it shrinks to one-third of its original diameter as the inner adhesive melts and flows, forming a marine-grade 360° watertight seal that protects connections from saltwater, corrosion, and moisture.
Shrink Ratio: 3:1
Voltage Rating: 600V
Operating Temp: -55°C ~ 125°C (-67°F ~ 257°F)
Full Shrink Temp: 110°C (230°F)
Perfect for automotive wiring, boat repairs, electrical maintenance, and DIY projects.
