Heat Shrink Tubing Black 3:1 Marine Grade Wire Wrap Adhesive Glue Lined Waterproof

Heat Shrink Tubing Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? waterproof heat shrink tubing is an easy to use solution that can be used in automotive, marine, hobby RC, and home electrical wiring projects. It can be used in a variety of applications such as: Electrical insulation (wire repairs, insulating electrical terminals wires, protecting charging cables, insulating solder joints)Environmental seal to protect from moisture, UV and fuelStrain relief for electrical terminalsIdentifying wires and cables (color-coding)Grouping loose wires (usually in wire harnesses)Creating thermal insulation for heat sensitive componentsProtecting surfaces against abrasion, peeling, and denting3:1 Shrink Ratio Shrink Tube When heat is applied, this wire shrink wrap tubing will recover to a 1/3 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing connectors. Therefore, 3:1 shrink ratio tubing can be used in significantly more applications compared to 2:1 shrink ratio tubing. Additionally, 3:1 marine heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps.
