Its heat-activated adhesive ensures waterproof, corrosion-resistant connections, while the dual wall design offers enhanced abrasion resistance and strain relief. With seven commonly used sizes pre-cut for convenience, this kit is ideal for automotive, marine, and electrical projects requiring durable, reliable insulation. ## Description Creates a waterproof seal Greater tensile strength Resistant to stretch and vibration Recovers to 1/3 of its original diameter More versatile compared to 2:1 tubing Stays flexible Connection is sealed from the elements Protection against wire corrosion Can be submerged under water Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? 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 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. 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 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. This industrial grade heat shrinkable tubing is UL listed and is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001. 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). Wirefy is a small USA owned an operated business. We offer top quality electrical connectors, crimping tools, heat shrink tubing and electrical wires at reasonable prices. Wirefy empowers electricians and DIY lovers to make professional electrical connections through quality products and education. We've got you covered on your wiring project. We craft our electrical connectors from thick, pure copper for strong crimps and max current flow. Tin coating protects against corrosion. Our terminals are marine grade & waterproof. Our crimping tools come with high precision crimping dies designed specifically for every terminal type. Our tools ensure consistent, effortless and rock solid crimps. Go for 3:1 or 4:1 shrink ratio. This ensures a tighter seal. Make sure it has adhesive lining for protection again dust & water. ## 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, creating waterproof and long-lasting insulation. - VARIETY OF SIZES - We have included 7 most commonly used diameters ranging from 3/32" to 3/4". Shrink tubing is precut to 3.5 inches. - EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Professional connections made in seconds. - DUAL WALL TUBING - Outer wall provides abrasion resistance. Inner wall creates waterproof seal and strain relief. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B084GDLSCK | | Best Sellers Rank | 34,312 in Business, Industry & Science (See Top 100 in Business, Industry & Science) 155 in Heat-Shrink Tubing | | Brand | Wirefy | | Customer Reviews | 4.6 4.6 out of 5 stars (24,849) 4.6 out of 5 stars | | Global Trade Identification Number | 00857409007471 | | Item Dimensions L X W | 19.5L x 3.5W centimetres | | Item Length | 19.51 Centimetres | | Manufacturer | Wirefy | | Material | Polyolefin | | Model Number | Wirefy-DWT-180 | | Number Of Packs | 1 | | Part Number | Wirefy-DWT-180 | | Recommended Uses For Product | Automotive, Marine, Outdoor, Electrical, Critical Automotive and Electrical Applications | | Unit Count | 1.0 count | | Upc | 857409007471 | ## Product Details - **Brand:** Wirefy - **Global Trade Identification Number:** 00857409007471 - **Material:** Polyolefin - **Product dimensions:** 19.5L x 3.5W centimetres - **Recommended uses for product:** Automotive, Marine, Outdoor, Electrical, Critical Automotive and Electrical Applications ## Images ![Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Heat Shrink Wire Tubing - Image 1](https://m.media-amazon.com/images/I/710zVlqXIYL.jpg) ![Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Heat Shrink Wire Tubing - Image 2](https://m.media-amazon.com/images/I/81L06TJ400L.jpg) ![Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Heat Shrink Wire Tubing - Image 3](https://m.media-amazon.com/images/I/7175FwIA2LL.jpg) ![Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Heat Shrink Wire Tubing - Image 4](https://m.media-amazon.com/images/I/718qqAxzpTL.jpg) ![Wirefy Heat Shrink Tubing Kit 180 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black - Shrink Wrap Tubing | Heat Shrink Wire Tubing - Image 5](https://m.media-amazon.com/images/I/71WLgzBobhL.jpg) ## Available Options This product comes in different **Color, Size** 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 ### ⭐⭐⭐⭐⭐ Excellent value and worries a treat *by on Reviewed in the United Kingdom 23 July 2026* Very good value and does exactly what it is supposed to do ### ⭐⭐⭐⭐⭐ Good shrink rate probably a genuine 3:1 or better.Strong and thick with good glue. Worth he extra *by on Reviewed in the United Kingdom 31 October 2025* These are great. Really pleased. I managed to wrap a 1mm cable with these. The shrink rate is good and they're thick so they should insulate well. The glue also works well. They are expensive but the job looks tidy and they should last me for years. ### ⭐⭐⭐⭐ Good quality. *by on Reviewed in the United Kingdom 19 December 2025* This brand makes good quality heat shrink.
