Every job entails requiring either partial or complete. I have been using ES-1 heat shrink. This is what the OEM’s provide in their harness and pigtail repair kits. It works great, but it can be really hard to find, and expensive once you do. I ran out recently and could not wait for my source to ship. So I decided I would try some of this product. Well, I’m pleasantly surprised. This Wirefy product is a perfect replacement. It has similar shrink ratio, strength, flexibility, and adhesive qualities to the OEM product. There is possibly a minuscule amount less adhesive in the Wirefy product but there is plenty to create a waterproof seal on a pair of wires sealed in parallel. I’m sold and will be using the Wirefy product on all my projects from now on. Review: Very good quality... adhesive lined is worth getting - I never realized how important getting adhesive lined wire shrink tubing was. It works great, and prevents the shrink tubing from sliding up and down. Also helps keep moisture out, which causes corrosion. Impressed with quality of wirefly shrink tubing and at a great price too! ## Features - 4:1 SHRINK RATIO - Recovers to 1/4 of its original diameter, and makes a tight seal.

Was thinking about using this to cover flare fittings on a mini-split hvac for support.** A: Hi, Yes, our heat shrink tubing is air tight. If you have any other questions, please feel free to send us a direct message. **Q: what size should i get to fit (3) 10AWG wires to make an extension cord ?** A: Depending on the type of wire and how thick the casing on the 10 gage wire. You might get away with 3/8 but I think it would be very tight, especially if long. So be safe and use 1/2 inch.. You will b fine. Look a the wire you are getting at its specs. It should tell you major dia. Add the 3 up. 2/3rds of you total will be bare minimum . But remeber if you make it to tight before shrinking. It will be hard to slide wire through. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff does it all! *by R***Y on June 20, 2022* I’ve been building Jeeps and rods for many years.
