Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using. Lots of different colours and size choice and inexpensive. Seal onto wire with a low flame on the blow lamp. But heat gun equally as good. Review: Good shrink rate probably a genuine 3:1 or better.Strong and thick with good glue. Worth he extra - 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. ## 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 1.75 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 | B084GWYX42 | | Best Sellers Rank | 14,687 in DIY & Tools ( See Top 100 in DIY & Tools ) 10 in Tubes (DIY & Tools) | | Brand | Wirefy | | Colour | Black, Red, White, Clear, Blue | | Country of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (29,142) | | Item Dimensions L x W | 44L x 44W millimetres | | Item Length | 1.75 Inches | | Item Weight | 20 Grams | | Manufacturer | Wirefy | | Material | Polyolefin | | Maximum Pressure | 10 Bars | | Nominal Wall Thickness | 2.11 millimeters | | Outside Diameter | 19.05 Millimetres | | UPC | 857409007464 | | Unit Count | 275.0 count | ## Product Details - **Brand:** Wirefy - **Colour:** Black, Red, White, Clear, Blue - **Item length:** 1.75 Inches - **Item weight:** 20 Grams - **Material:** Polyolefin - **Maximum pressure:** 10 Bars - **Nominal wall thickness:** 2.11 millimeters - **Outside diameter:** 19.05 Millimetres - **Product dimensions:** 44L x 44W millimetres - **UPC:** 857409007464 ## Images ![Heat Shrink Tubing Kit - Heatshrink Sleeving Kit - 3:1 Ratio Adhesive Lined - Marine Grade Shrink Wrap - Wire Cable Repair Sleeve - Automotive Industrial Tubing - 275 PCS - Image 1](https://m.media-amazon.com/images/I/81MovjxTFUL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Do you sell these kits without the adhesive lining?** A: At the moment we do not offer heat shrink tubing kits without adhesive lining. **Q: Can a hair dryer be used to heat the tubes?** A: Thank you for your question. We recommend using a heat gun as a heat source. **Q: what would be the correct size for 6242Y grade 2.5mm twin and earth cable? the cable measure 10mm x 5mm** A: If you are electrical engineer by trade your ansawer to your question should be why. Why are you using this shrink wrap on any type of twin & earth. If its been cut or broken then unless you have good knowledge of ac cabling and I presume you're competently qualified in this I would not suggest using it in any ac environment. By way of your disciption, if there is some kind of brake or join in two wires (cables) you would normally solder the joints and shrink wrap the joint to seal and secure. If in case of ac use only a joiner like waggo ect which is rated appropriately, if in doughty with any ac diy activity seek qualified abilities, you may only regret it soon or later if you don't. A bodge can kill😕🤔 **Q: Is this suitable for use in an aquarium?** A: It’s plastic so pretty inert. It depends on what you want to do with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ would recommend these *by R***2 on 29 August 2025* a must to have on hand in the shop.
