## Questions & Answers

**Q: Can this sealant be used with propane**
A: Good question? 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

### ⭐⭐⭐⭐⭐ Excellent pipe dope.
*by T***D on March 15, 2023*

Using this on a vacuum steam product with temperatures up to 200° f. I find it does an excellent job at lubricating the stainless steel fittings and when I remove fittings there's still plenty of dope on the threads helping to make a good seal. The steam rating and vacuum rating were very important to me and this product does the job well! Must be the Kevlar bits ... But whatever it is that makes it work, it's superior to the loctite product I was using before in both lubrication qualities, sealing ability, and durability. I highly recommend it.

### ⭐⭐⭐⭐⭐ Closes up the tough leaks
*by J***F on 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.

### ⭐⭐⭐⭐ Even works on wet fittings
*by A***R on December 12, 2022*

Works on wet pipe fittings when doing repairs. Holds up well and worked good In aiding for removal of fittings years later.
