Its dual-wall, marine-grade polyolefin construction offers superior resistance to heat, fluids, and mechanical wear, making it ideal for professional electrical insulation, automotive, marine, and hobby applications. The 50-foot roll provides ample length for multiple projects, certified UL for safety and reliability. ## Description Super Versatile Heat Shrink Tubing 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, fuel and chemicals -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 connectors. Therefore, 4:1 shrink ratio tubing can be used in significantly more applications compared to 2:1, and 4:1 shrink ratio tubing. Heat Activated Adhesive Lining This is a waterproof shrink tubing with the internal adhesive layer. When heat is applied, a small fillet of clear adhesive (about 1 mm wide) becomes visible at the ends of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly bonds 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. 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. ## Features - 4:1 SHRINK RATIO - Recovers to 1/4 of its original diameter, and makes a tight seal. Highest heat shrink ratio on the market. - GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection. This creates waterproof 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. Marine grade tubing is resistant to fluids, heat, and mechanical stretch. - 1-1/4" (32.0mm) SHRINK TUBING DIAMETER - Get the exact diameter you need. 50 Feet of shrink tubing will last through many projects. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Wirefy | | Part Number | Wirefy-DW41-32-Red | | Product Dimensions | 31.9 x 5.21 x 31.9 cm; 1.51 kg | | Item model number | Wirefy-DW41-32-Red | | Size | 1-1/4" - 50 Feet | | Colour | Red | | Style | Red | | Material | Polyolefin | | Voltage | 600 Volts | | Item Package Quantity | 1 | | Certification | UL | | Usage | Electrical insulation, Environmental seal, Strain relief, Wire identification, Grouping loose wires, Thermal insulation, Surface protection, Automotive, Marine, Hobby RC, Home electrical wiring | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 1.51 kg | ## Product Details - **Brand:** Wirefy - **Material:** Polyolefin - **Colour:** Red - **Outside diameter:** 32 Millimetres - **Item length:** 5E+1 Feet - **UPC:** 850026973433 - **Manufacturer:** Wirefy - **Specific uses for product:** (function(f) {var _np=(window.P._namespace("DetailPageProductOverviewTemplatesJava"));if(_np.guardFatal){_np.guardFatal(f)(_np);}else{f(_np);}}(function(P) { P.when('A').execute(function(A){ A.on('a:truncate:po-attribute-truncate-7:updated', function(data) { var isTruncated = !data.truncateInstance.getIfTextFits(); var seeMoreElement = document.getElementById('po-attribute-see-more-id-7'); if(seeMoreElement) { seeMoreElement.style.display = isTruncated ?
