Specification Brand : TKDMR BulletPoint1 : 1.Pakage Included: Upgrade 446pcs 4:1 Ratio,7 most commonly used diameters ranging from 3/32" to 3/4". Shrink tubing is precut to 1.75" inches. BulletPoint2 : 2.High Shrinkage Ratio: 4:1 SHRINK RATIO, it can shrink to 1/4 of the original diameter,Shrink tighter and seal better than 3:1 and 2:1. Suitable for more application.the shrinkage temperature is 125°C (257°F), and the withstand voltage is 600V.Wire Cable shrink wrap.High flame retardant coefficient. BulletPoint3 : 3.Glue Inside: Shrink Tubing for Wires,When the Heat-shrink tube shrinks, the glue film on the inner wall will melt and then it will be adsorbed on the surface of the object tightly so as to connect tightly, insulate, and seal off perfectly. Eliminates the problem of 3:1 and 2:1 tubing not shrinking tight enough. It has the advantages of waterproofing, moisture-proof, wear-resistant, anti-skidding, heat-resistant, tensile-resistant, anti-aging, and corrosion resistance. BulletPoint4 : 4.Easy to Use: Only need to cut the required size heat shrinkable tube, slide it to the required position and then use the hot air gun so that the professional insulation connection is completed in a few seconds finaly. BulletPoint5 : 5.Wide Range of 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. Color : Black CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier1 : 086429108220 ExternallyAssignedProductIdentifier2 : 0086429108220 ExternallyAssignedProductIdentifier3 : 00086429108220 IncludedComponents : Heat Shrink InstallationType : Self-Adhesive ItemLength : 40 inches ItemName : TKDMR 446 Pcs Heat Shrink Tubing Kit - 4:1 Ratio Adhesive Lined, Marine Grade Shrink Wrap - Industrial Heat Shrink Tubing,Black ItemPackageDimensions_Height : 19.812 centimeters ItemPackageDimensions_Length : 3.81 centimeters ItemPackageDimensions_Width : 13.589 centimeters ItemPackageQuantity : 446 ItemTypeKeyword : heat-shrink-tubing Manufacturer : TKDMR Material : Polyethylene ModelNumber : a20112100ux0177 NominalWallThickness : 6.4 month NumberOfBoxes : 1 NumberOfItems : 1 PackageLevel : unit PartNumber : 41568TD ProductDescription : 1.Pakage Included: Upgrade 446pcs 4:1 Ratio,7 most commonly used diameters ranging from 3/32" to 3/4".
