Wirefy 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 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 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. Heat Activated Adhesive Lining This is a waterproof 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 waterproof. For best results we recommend using a heat gun. Dual Wall Shrink Tubing Dual wall marine grade 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 flame retardant. UL Listed This industrial grade heat shrinkable tubing is UL listed and 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, white, blue, clear). Review: Recommended - I'm now on my 2nd box of these heat shrink tubes. I find them very good quality, they have a good shrink ratio, and the adhesive creates a good water proof seal. Used for amateur radio antennas and electronic repairs / projects. Review: would recommend these - a must to have on hand in the shop. Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using. Lots of different colours and size choice and inexpensive. Seal onto wire with a low flame on the blow lamp. But heat gun equally as good. ## Features - 3:1 Shrink Ratio: Wirefy heat shrink tubing recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough. - Glue Inside: When heat is applied, adhesive comes out and seals the connection, creating waterproof and long-lasting insulation. - Variety of Sizes: We have included larger diameter heat shrink tubing ranging from 1/8" to 1". Shrink tubing is precut to 1.75 inches. - Easy to Use: Simply slide the heat shrink tube over your connection point and apply heat. Professional connections made in seconds. - Dual Wall Tubing: Outer wall of the heat-shrink tubing provides abrasion resistance. Inner wall creates waterproof seal and strain relief. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089D82FLG | | Best Sellers Rank | 951 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 7 in Heat-Shrink Tubing | | Brand | Wirefy | | Colour | Black, Red | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 29,359 Reviews | | Item Dimensions L x W | 19.5L x 13W centimetres | | Item Length | 7.68 Inches | | Item Weight | 249 Grams | | Item weight | 249 Grams | | Manufacturer | Wirefy | | Material | Polyolefin | | Maximum Pressure | 4 Bars | | Maximum pressure | 4 Bars | | Nominal Wall Thickness | 3 millimeters | | Outside Diameter | 2 Millimetres | | Product dimensions | 19.5L x 13W centimetres | | UPC | 857409007969 | | Unit Count | 200.0 count | ## Product Details - **Brand:** Wirefy - **Colour:** Black, Red - **Item length:** 7.68 Inches - **Item weight:** 249 Grams - **Material:** Polyolefin - **Maximum pressure:** 4 Bars - **Nominal wall thickness:** 3 millimeters - **Outside diameter:** 2 Millimetres - **Product dimensions:** 19.5L x 13W centimetres - **UPC:** 857409007969 ## Images ![– Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - Larger Diameter - 3:1 Dual Wall Tube - Adhesive Lined - Wire Cable Repair Sleeve - Black Red - 200 PCS - Image 1](https://m.media-amazon.com/images/I/81wNRgHdFTL.jpg) ![– Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - Larger Diameter - 3:1 Dual Wall Tube - Adhesive Lined - Wire Cable Repair Sleeve - Black Red - 200 PCS - Image 2](https://m.media-amazon.com/images/I/81Lh-SSH1OL.jpg) ![– Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - Larger Diameter - 3:1 Dual Wall Tube - Adhesive Lined - Wire Cable Repair Sleeve - Black Red - 200 PCS - Image 3](https://m.media-amazon.com/images/I/71dvIKWvEAL.jpg) ![– Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - Larger Diameter - 3:1 Dual Wall Tube - Adhesive Lined - Wire Cable Repair Sleeve - Black Red - 200 PCS - Image 4](https://m.media-amazon.com/images/I/718qqAxzpTL.jpg) ![– Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - Larger Diameter - 3:1 Dual Wall Tube - Adhesive Lined - Wire Cable Repair Sleeve - Black Red - 200 PCS - Image 5](https://m.media-amazon.com/images/I/71MKZWqu9XL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Hi what size heat shrink do i need for 16mm2 and 35mm2 battery cable ?** A: this pack has the sizes you need. **Q: Would a hair dryer work in lieu of a heat gun.** A: I think it will work as long as the hair dryer gets really hot ? It will take longer obviously.... But, any heat gun will work and they aren't very expensive. **Q: Can it be used on shoe laces** A: That's an interesting question! It's certainly adhesive inside, and the cable joins I do seem robust, so I suspect the answer is yes, although it is quite stiff and will be slightly proud of the original lace so it may not sit on the shoe very vell. I presume that the adhesive is primarily to seal against water entry, so I don't know what the pull strength will be. **Q: Is the width shown really the diameter or the width when flat, i.e is the largest one 25.4mm (1") diameter or 16mm (0.6") diameter?** A: Width when its unshrunk very good heat shrink product worth getting ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommended *by L***E on 14 July 2025* I'm now on my 2nd box of these heat shrink tubes.

But heat gun equally as good. ### ⭐⭐⭐⭐ Handy selection of sizes in clear tubing *by R***. on 6 July 2023* Most heat shrink tubing is coloured (usually black) so you cannot see what you have put the tubing over. There are times when you need to see what the tubing has been placed over. I intended to use some to put over some USB sticks to make the identifying label more permanent. Unfortunately I underestimated the size of the USB stick so only the largest ones would fit. Worked well in this application. The others will be added to the general use pile. ## Frequently Bought Together - Wirefy Heat Shrink Tubing Kit - 3:1 Ratio Adhesive Lined, a resistant Shrink Wrap - Automotive Industrial Heat-Shrink Tubing - Black, Red - 200 PCS - SELTERM 10pcs - 2 Awg - 5/16" Stud - Battery Lugs - Ring Terminal Connectors | with 12pcs 3:1 Black & Red Heat Shrink Tubing with Adhesive | Heavy Duty Battery Cable Ends - Tinned Copper Wire Lugs Kit - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing --- ## 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.vu/products/286807756-heat-shrink-tubing-kit-heatshrink-sleeving-kit-larger-diameter-3](https://www.desertcart.vu/products/286807756-heat-shrink-tubing-kit-heatshrink-sleeving-kit-larger-diameter-3) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-07*
