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: You pay for quality - Good quality but pricey, but if you are protecting electrics, then this is the one. Wish it came in shorter lengths, so I could have gotten a size down too. Shrinkage is uniform, have to cut open to re do and the wire comes away neatly which is also a bonus. Very durable but measured diameter wrong, but that's on me. I've used this on all my bikes wiring and seems solid so far. Review: Very high quality. Used for aluminium pole repair. - I had a snapped and bent aluminum boat canopy frame which I had straightened and repaired with tube inserts and rivets. Fine as far as it goes but I had the bright idea of encasing it in heat shrink to prevent any rough spots damaging the canopy, and to disguise the agricultural nature of the repair in general. I tested several different types of heat shrink, and this one is the clear winner. It is nice and thick, looks great, and I was able to shrink 5 metres of it with a blowtorch without scorching it at all. Add to that its excellent substrate of hot glue, and it's even strengthened the poles somewhat by laminating them. I'm absolutely delighted with the result, which would not have been possible with an inferior product. ## Features - 3:1 SHRINK RATIO - 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. This creates resistant and long-lasting insulation. - EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds. - DUAL WALL TUBING - Provides enhanced protection from wear and tear. a resistant tubing is resistant to fluids, heat, and mechanical stretch. - 3/4 INCH (19.1mm) SHRINK TUBING DIAMETER - Get the exact diameter you need. 50 Feet of shrink tubing will last through many projects. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08W8BMP4G | | Best Sellers Rank | 124,642 in DIY & Tools ( See Top 100 in DIY & Tools ) 69 in Tubes (DIY & Tools) | | Brand | Wirefy | | Colour | Black | | Customer Reviews | 4.7 out of 5 stars 2,744 Reviews | | Item Dimensions L x W | 19W millimetres | | Item Length | 15.25 Metres | | Manufacturer | Wirefy | | Material | Polyolefin | | Maximum Pressure | 10 Bars | | Maximum pressure | 10 Bars | | Nominal Wall Thickness | 1,25 inch | | Nominal wall thickness | 1,25 inch | | Outside Diameter | 19.1 Millimetres | | Product dimensions | 19W millimetres | | UPC | 850026973068 | | Unit Count | 15 meter | ## Product Details - **Brand:** Wirefy - **Material:** Polyolefin - **Colour:** Black - **Product dimensions:** 15.24L x 0.02W metres - **Maximum pressure:** 10 Bars - **Nominal wall thickness:** 1,25 inch - **Outside diameter:** 19.1 Millimetres - **Item length:** 600 Inches - **UPC:** 850026973068 - **Manufacturer:** Wirefy ## Images ![Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll - Image 1](https://m.media-amazon.com/images/I/81rdOCp7Z6L.jpg) ![Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll - Image 2](https://m.media-amazon.com/images/I/71NCe6hoqRL.jpg) ![Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll - Image 3](https://m.media-amazon.com/images/I/7175FwIA2LL.jpg) ![Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll - Image 4](https://m.media-amazon.com/images/I/71lsJeA7PjL.jpg) ![Wirefy 3/4" Heat Shrink Tubing - Large Diameter - 3:1 Ratio - Adhesive Lined - Industrial Heat-Shrink Tubing - Black - 50 Feet Roll - Image 5](https://m.media-amazon.com/images/I/71iQj19RX+L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How flexible is the heat shrink once recovered? I am using it to group wires for a wiring loom/harness and my current heat shrink is very inflexible.** A: Probably the best one have ever tried not over flexible but not as brittle as over ones.little tip all ways try to use the smallest size you can as less shrinking the more flexibility it retains. **Q: Does it come in white** A: Its available in Red and Black. **Q: Is the tubing black or does it have printing on it all along the tubing ?** A: Thank you for your question. The tubing is black and there is printing on it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ You pay for quality *by P***E on 5 September 2025* Good quality but pricey, but if you are protecting electrics, then this is the one.
