See technical specs here: https://www.fedprobrands.com/products/pipe-thread-sealants/gasoila-e-seal-thread-sealant.html **Q: Is this appropriate for fittings on a dispensing pump for diesel fuel?** A: It’s about the best I’ve found for any diesel or gasoline engine application. **Q: Will this work on gas tank drain plug that is leaking slightly??** A: Depends on why the plug is leaking. If the plug is threaded and the threads are damaged, probably not. If by "slightly" you mean weeping and if the threads are ok, then it may be sufficient. The reason that I used Gasoila E-seal was because of its resistance to degradation by Ethanol, especially in high percentage Ethanol/Gasoline blends. The product is a sealer, not a glue or filler. **Q: Has anyone used this on fittings that are exposed to engine oil?** A: It is rated for use with ethanol gasoline. Ethanol is much more harsh than engine oil. I would just avoid getting it inside an engine. ## Frequently Bought Together - Gasoila Thread Sealant for Ethanol E10 & E85 Applications, Non-Hardening, Non-Toxic, Opaque Dark Green Paste – USA-Made, 1/4 Pint – Ideal for Pipe Threads, Motors, Fuel Lines & More, Brush in Cap - Gasoila Soft-Set Pipe Thread Sealant – Non-Hardening Paste for Metal & Plastic, 1/2 Pint with Brush Cap – Reliable Leak Prevention, Drip-Resistant, Temp Range -100 to 600°F, Made in USA - Gasoila Yellow PTFE Thread Seal Tape – Professional-Grade, 1/2 Inch x 260 Inch, High-Density Thread Tape for Gas Lines– Leak-Proof Seal, Non-Toxic --- ## 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.nl/products/6359719-thread-sealant-for-ethanol-e10-and-e85-applications-non-hardening](https://www.desertcart.nl/products/6359719-thread-sealant-for-ethanol-e10-and-e85-applications-non-hardening) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-05-11*
