The 3:1 shrink ratio gave a tight, perfect seal over the connections, keeping the harness slim enough to pull through the bars effortlessly. ​Excellent Heat Tolerance: It handles heat incredibly well during application. It shrank down evenly without burning, splitting, or getting brittle, and the internal adhesive flowed perfectly to create a solid, weatherproof barrier. ​Top-Tier Quality: The thick, marine-grade wall offers awesome abrasion resistance inside the bars where things can rub. ​If you're doing any internal motorcycle wiring or bar swaps, don't hesitate—this stuff is top-tier. Review: Honey, I Shrunk The Wraps - Today’s purchases are four foot rolls of both black and red large heat shrink for electrical applications. They came sealed and packed together. I wanted red and black heat shrink for my car audio installations. This purchase allowed me to conveniently buy, not only both red and black together, but the rolls allow me to cut them as long or as short as I need at the moment. I used them to distinguish between the power and ground wires since the insulation is the same color. It also made the install much cleaner looking and protected the install from shorts. These sheat shrinks seem to have an additional adhesive on the inside, meaning once they are on, they are not coming off. This is really great for securely protecting your equipment, but not so great if you have to remove them. I recently started getting into using the heat shrinks, but now that I am, I want everything to have shrink on it. These tubes are super easy to use and work on a wide range of sizes, shrinking up to four times. The quality and results that you get from these are great, and they are very affordable, making them a very good deal. If you like using heat shrink, and you are looking to get some or replenish your stock, I would highly recommend these, because they are a great value. ## Features - The Round Diameter is 3" / 80mm (Before Shrinking) and 1" / 25.4mm (After Shrinking).

Compatible with pretty much anything. Super easy to use. use a heat gun and it shrinks and adheres perfectly. for the price I wish I got 10ft. ## Frequently Bought Together - ELECFUN 3 Inch Heat Shrink Tubing Roll, 3:1 Large Marine Grade Adhesive Lined Heatshrink Tube, Heavy Duty Dual Wall Shrinkable Wiring Wrap, Seal Against Moisture Corrosion and Air Leakage 4 ft - XHF 2 Inch (50mm) 3:1 Waterproof Heat Shrink Tubing Marine Grade Wire Cable Adhesive Lined Tube Insulation Seal Against Moisture Corrosion and Air Leakage, 4 Ft Black - 2 Inch Heat Shrink Tubing - 5 Ft 3:1Ratio Waterproof Heat Shrink Tubin - Adhesive Lined,Dual Wall Adhesive Shrinkable Wire Wrap Tube - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/489810029-3-inch-3-1-large-marine-grade-adhesive-lined-heat](https://www.desertcart.sc/products/489810029-3-inch-3-1-large-marine-grade-adhesive-lined-heat) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-24*
