Most propane connection are either flare or pipe thread , did you read the spec’s ? I use Mega for pvc /abs waste slip connections and flange arm / nipples with treaded ends. For all my gas connections I use Rector Seal or yellow gas pipe Teflon thread tape **Q: Can this product be used as a thread sealant on diesel fuel applications? Any literature?** A: I’d rather go with another thread sealants specially designed for fuels, there are few of them and very reliable **Q: Can MegaLoc be used to seal the threads on the various fuel tank fittings on an aftermarket auxiliary fuel tank that wil be carrying diesel fuel ?** A: yes, works great for that. just makes sure threads are clean when you start. **Q: Based on the title description, this product is not the same as the picture. Can you please identify which is correct?** A: The product I received is the same as the one in the photo (Megaloc 15804) but it is for the 4oz size, not the 8oz shown in the main photo. If you scroll down it shows the 4oz size. I agree that this is misleading and therefore I just paid about twice what I expected to pay for this product 😑 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work the BEST ! *by on Reviewed in the United States August 16, 2026* This stuff is the only thing you need for all plumbing joints ### ⭐⭐⭐⭐⭐ Prevent gas wash out *by on Reviewed in the United States July 22, 2026* Great for gas fitting from seizing. My 3 2's Hollies have 9 fitting . You don't want to see the metal tube start to twist. Put on the tube flare to prevent with gas resistance tape to keep from gas wash out! ### ⭐⭐⭐⭐⭐ Closes up the tough leaks *by on Reviewed in the United States June 9, 2025* This compound has the perfect properties. Used it on some plastic parts, which often do not seal well and are risky to overtighten. Well worth getting this product. One bottle will last a lifetime for DIYers. ## Frequently Bought Together - Hercules 15808 Megaloc Multi-Purpose Thread Sealant, 16 Oz, Can, Blue, Liquid Paste, Bule, 16 Fl Oz - Hercules Megatape Gray 1/2 in.
