Wirefy resistant heat shrink tubing is an easy to use solution that can be used in automotive, 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 fuel Strain relief for electrical terminals Identifying wires and cables (color-coding) Grouping loose wires (usually in wire harnesses) Creating thermal insulation for heat sensitive components Protecting surfaces against abrasion, peeling, and denting 4:1 Shrink Ratio Shrink Tube When heat is applied, this wire shrink wrap tubing will recover to a 1/4 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing larger connectors. Therefore, 4:1 shrink ratio tubing can be used in significantly more applications compared to 3:1 and 2:1 shrink ratio tubing. Additionally, 4:1 heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps. Heat Activated Adhesive Lining This is a resistant shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection resistant. For best results we recommend using a heat gun. Dual Wall Shrink Tubing Dual wall heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is perfect for everyone. This industrial grade heat shrinkable tubing is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001. Our Collection of Heat Shrink Tubing Wirefy assorted heat shrink tubing comes in kits as well as 50 Ft rolls. We offer a great variety of sizes (3/32” to 2”) and colors (black & red). Review: Great product - This stuff works great.Not just for wiring,I’ve used it to insulate tool handles, patch cracked or chafed or otherwise damaged outer sheathing of brake or clutch cables on bikes etc.I’ve ordered several sizes of the rolls and multiple boxes of the pre-cut assorted sizes over the past few years. Comes either 3:1 or 4:1 shrinkage rates . Once you figure out what you use the most it’s great to be able to get 20-25’ rolls . It has adhesive on the interior that really makes a great seal for keeping moisture out.There may be comparable products out there but I am going to continue to use this brand. I think the price is fair and you get what you pay for. Review: Nice kit, lots of sizes - They shrink smaller than most shrink tubing which is nice. ## Features - 4:1 SHRINK RATIO: Recovers to 1/4 of its original diameter, and makes a tight seal.

I hope this helps! You can contact us directly if you need more info. **Q: Can it be used with self regulating heat cable** A: Hi, We do not recommend it because it will generally be kept at a higher temperature, up to 120℃, occasionally as high as 175℃. **Q: Can this be used to cover banana plugs in use with speaker wire?** A: Thank you for your question. Yes, it can be used to cover banana plugs in use with speaker wire. **Q: Can these be used to reinforce the wire leading to earbuds? The rubber has ripped exposing a small window of the wires.** A: You could if you are very careful as the heat needed to use for these could very easily melt the wires for your ear buds. You may be better off using liquid tape. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***M on February 1, 2026* This stuff works great.Not just for wiring,I’ve used it to insulate tool handles, patch cracked or chafed or otherwise damaged outer sheathing of brake or clutch cables on bikes etc.I’ve ordered several sizes of the rolls and multiple boxes of the pre-cut assorted sizes over the past few years.

I was rewiring heavy gauge cable for a new bow mount trolling motor, and despite some neg reviews I decided to purchase anyway. I'm not disappointed, these worked out great. they shrunk down tight and with the internal adhesive they created a very watertight seal on all connections. I would recommend these to friends as well as purchase them again in the future. ## Frequently Bought Together - Wirefy Heat Shrink Tubing Kit 190 PCS - 4:1 Ratio Adhesive Lined - Adhesive Heat Shrink with Glue - Black & Red - Heat Shrink Tube Kit, Heat Shrink Assortment, Waterproof Heat Shrink Tubing - Wirefy 200 PCS Non Insulated Butt Connectors Kit - Butt Splice Connectors - Uninsulated Crimp Wire Connectors - 24-8 AWG - Eventronic 400 Pcs Heat Shrink Tubing Kit-3:1 Ratio Adhesive Lined,Marine Grade Shrink Wrap - Industrial Heat-Shrink Tubing - Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/426084227-heat-shrink-tubing-kit-4-1-ratio](https://www.desertcart.tn/products/426084227-heat-shrink-tubing-kit-4-1-ratio) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
