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 3:1 Shrink Ratio Shrink Tube 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. Heat Activated Adhesive Lining 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 Shrink Tubing 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. 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. Our Collection of Heat Shrink Tubing 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). Review: would recommend these - a must to have on hand in the shop. 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.

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 ### ⭐⭐⭐⭐⭐ would recommend these *by R***2 on 29 August 2025* a must to have on hand in the shop.
