I have 1/4'', 3/8'', & 1/2'' and they all measure at least their diameter before shrinking. I won't use anything but Wirefy tubing! I like the 3:1 best for my uses. **Q: what is the operating temperature rating?** A: From my use it appears to have an operating temperature of between 600F and 900F. Unless the tubing is physically contacting a heat source I would say its save to use at near 1000F. Within 1/8" from a industrial soldering iron that idles at 980F It is safe. It may over-harden if exposed to this level of heat for a length of time (Over 30 min.) Contact heat will burn this at even a low temp.( i.e. laying across an engine's exhaust manifold. It would would work well in nearly any engine compartment. Hope this helps. For short runs this stuff is tough. **Q: Will it work on 14awg wire?** A: Yes, 3/16" heat shrink tubing will work on 14AWG wire. **Q: Is this heat shrink resistant to gasoline?** A: It is resistant to gasoline. However, we do not recommend to leave it submerged in gasoline. ## Frequently Bought Together - Wirefy 3/8" Heat Shrink Tubing - 3:1 Ratio - Adhesive Lined - Marine Grade Heat Shrink - Black - 50 Feet Roll | Wire Heat Shrink Tubing, Wire Shrink Wrap Tubing, Heat Shrink Wire Tubing - Wirefy 150 PCS Wire Spade Connectors - Female Spade Connector Heat Shrink - Quick Disconnect Wire Connectors - Electrical Spade Terminals - Female Spade Connector 16-14 Gauge | Blue Spade Connectors - Wirefy 200 PCS Heat Shrink Butt Connectors Red 22-16 AWG - Marine Grade Butt Connectors - Wire Butt Splice Connectors - Electrical Waterproof Heat Shrink Butts --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/386344254-wirefy-1-4-heat-shrink-tubing-3-1-ratio-adhesive](https://www.desertcart.tn/products/386344254-wirefy-1-4-heat-shrink-tubing-3-1-ratio-adhesive) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
