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. ## Frequently Bought Together - Wirefy 1/4" Heat Shrink Tubing - 4:1 Ratio - Adhesive Lined - Marine Grade Heat Shrink - 50 Feet Roll - Black - Wirefy 1/8" Heat Shrink Tubing - 3:1 Ratio - Adhesive Lined - a resistant Heat Shrink - Black - 50 Feet Roll --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/432838204-heat-shrink-tubing-roll-50-feet-4-1-ratio](https://www.desertcart.co.za/products/432838204-heat-shrink-tubing-roll-50-feet-4-1-ratio) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-15*
