## Overview

This 25-foot roll of 3/8 inch black heat shrink tubing features a superior 3:1 shrink ratio that tightens to one-third its original diameter, ensuring a secure, gap-free seal. Its dual-wall adhesive design provides waterproof protection and abrasion resistance, making it perfect for electrical insulation, corrosion prevention, and durable wire harnessing. Easy to apply and built to withstand high temperatures, this tubing is a must-have for professionals and DIY enthusiasts seeking reliable, long-lasting results.

## Description

3:1 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.

Review: I've already used this as grip on my pool stick, My kids baseball bats, and a fishing rod - Pretty good I don't know what the original use is for this but this works really good as a grip for a pool stick or fishing rod or anything like that as well Even a baseball bat maybe another market you could put in your categories
Review: Very Good Quality - I'm a retired professional mechanic who specialized in electrical. I installed stereos way back in the CB days. I've used lots and lots of heat shrink and and know a good quality shrink tubing that is thick with a sealant. The shrinkage was very good as is the durability. I used this for modifying the lighting on my motorcycles where I added some resisters. To hold them on the bike so I didn't have to drill holes, I used hose clamps to hold them against the frame. I slid the heat shrink onto the hose clamp for looks and added durability. I looked very good.
