Description

  • VERSATILE HEAT SHRINK TUBING: 334Pcs Marine Heat Shrink Tubing Kit, Pre-Cut 5 Sizes 2 Colors (Black/Red), Universal Common Diameters, ranging from 3/32" to 5/16". All of our heat shrink tubes are pre-cut to standard everyday usable lengths in various sizes. Ideal for a multitude of applications including automotive, marine, and home electrical projects. Perfect for repairing frayed wires, sealing out moisture, or providing strain relief. Our Dual Wall Adhesive Lined Heat Shrink Tubing Kit provides comprehensive, convenient, and reliable protection for all types of electrical connections.
  • 3:1 SHRINK RATIO: Our dual-wall adhesive heat shrink tubing features a 3:1 shrink ratio, shrinking down to 1/3 of its original diameter when heated (use a hot air gun—lighters are not recommended). It creates a snug, conforming fit over wire terminations, butt splices, exposed cable insulation, and even irregular or stepped profiles. This high shrink ratio eliminates loose spots and ensures full coverage, making it ideal for use with our 12-10Ga. 14-12Ga. 16-14Ga. 22-16Ga. 24-18Ga. and 26-22Ga. butt connectors, as well as a wide range of other wire sizes. Shrink temperature: 80-125°C; contracts quickly to deliver a professional connection in seconds, saving time and effort.
  • DUAL WALL CONSTRUCTION FOR SUPERIOR DURABILITY: Our dual-wall adhesive lined heat-shrink tubing features a robust dual-layer design that outperforms standard 2:1 single-wall tubing. Unlike 2:1 single-wall construction, which offers lower durability, weaker abrasion resistance, and reduced tensile strength, our dual-wall design delivers superior protection. The tough outer sleeve provides exceptional mechanical defense against abrasion, impact & wear, shielding your cables and connectors from damage in daily use or harsh environments. The soft, heat-activated inner adhesive layer ensures a tight, gap-free bond—working together to provide long-term durability and reliability you can count on.
  • HEAT-ACTIVATED INTERNAL ADHESIVE: Our dual-wall adhesive heat-shrink tubing: When heat is applied, the strong internal adhesive layer melts and flows uniformly around your cables, connectors, and wire terminations. This molten adhesive fills every gap and crevice, forming a permanent, form-fitting bond that locks the tubing securely in place—no slippage, no loose edges, and no gaps over time. The adhesive bond not only enhances the tubing’s hold but also lays the foundation for its superior sealing and insulation performance.
  • HERMETIC INSULATION & WATERPROOF SEALING: Our dual-wall heat-shrink tubing features a melted adhesive that forms a 100% hermetic, airtight, and watertight seal, effectively blocking moisture, dust, dirt, saltwater, and corrosion. This makes it essential for marine, automotive, and outdoor applications where connections are exposed to harsh elements. Meanwhile, the dual-wall structure delivers superior long-lasting electrical insulation, preventing short circuits, current leakage, and signal interference. It also offers excellent tensile strength, ensuring the seal and insulation remain stable under tension, vibration, and extreme temperature changes.
  • PERFECTLY PRE-CUT SIZES & READY TO USE: This Kit includes 334 Pcs dual wall polyolefin adhesive heat shrink tubing in Black & Red, all pre-cut to perfect lengths and neatly organized in a sleek, handy storage package. No tedious on-site cutting required—simply take the needed tubing and slide it into position, saving valuable time and effort on all wiring projects. The precision pre-cut design ensures consistent sizing, avoids material waste from improper cutting, and delivers a neat, professional finish for every connection, making it ideal for both professional electricians and DIY enthusiasts. Easy to store and quick to select the right size for any connection need.
  • EASY TO USE: Our heat shrink tubing comes Pre-Cut, so no trimming is needed—you can use it directly. Simply slide it into position and apply heat with a hot air gun. A professional insulated connection will be completed in just a few seconds. Using a lighter is not recommended. Direct flame can easily damage the underlying wire and cause uneven shrinkage of the tubing. Instead, apply heat evenly from multiple angles to achieve uniform shrinkage without overheating any section of the tubing.
  • VERSATILE APPLICATIONS: Heat shrinkable tubing is mainly used in data line ,industry, boats and ships, wire connections,rust and corrosion prevention of solder joints, audios, electrical equipment and DIY etc. Besides, it is also used in wire end, wire harness, electronic protection and insulation treatment, fitness equipment handle and steel structure surface protection etc.
  • MULTIPLE APPLICATIONS: Our waterproof dual-wall heat shrink tubing features a heat-activated sealant lining that forms a 360° secure hermetic seal. Ideal for sealing battery lugs, repairing charger cables, securing rope ends, and all crimped/soldered connections that demand a robust, long-lasting seal—suitable for automotive, marine, industrial, and household wiring projects. This all-in-one heat shrink tubing delivers comprehensive, convenient protection for all electrical connections, making it the perfect choice for any wiring repair, installation and maintenance work.
  • BUYER CONFIDENCE - Always match the size and gauge of terminals, cables, and lugs to ensure a proper fit. It’s important to use these connectors with compatible copper cables. We recommend double-checking the dimensions to confirm accuracy before purchasing—this ensures your connections are secure and long-lasting. If you encounter any issues, we stand ready to resolve them for you. Everything you need to get started is included here.
