Review: Excellent Sealant for Automotive Use! - used it to seal the differential plugs on my Ram 1500. It worked perfectly! The application was smooth and easy, and it provided a strong, leak-proof seal that gives me peace of mind. I really appreciate that it’s designed for high-temperature environments, which is essential for automotive applications. After driving for a while, I’ve had zero leaks and everything is holding up great. The tube size is convenient and has plenty of product for multiple uses. If you need a reliable, high-performance thread sealant for your vehicle, this is an excellent choice. Highly recommend for anyone doing differential or drivetrain work!
Review: Great Seal, Great Heat Resistance - I was installing a three-way valve and I didn’t have the means to pressure test my threaded connections until everything was threaded and sweated in place. Once the rest of the fittings were sweated together, I couldn’t tighten the threaded connections. The first time around, I used teflon tape and it didn’t work well. Next, I tried this permatex sealant because it would make a permanent anaerobic seal, and it can withstand sweating connections nearby. It worked great! The connection has been holding for months now with no water leaks. I recommend wearing nitrile or latex gloves when handling, it’ll let you work more quickly and cleanup easier.

## Questions & Answers

**Q: How hard is to unscrew after this has been set for awhile?**
A: Comes apart with minimal force, it is a sealant not a thread locker. It works especially well on sealing thread that are not tapered pipe threads. I use this on my harley fluid drain plugs

**Q: Does this product solidify after 72 hrs as cited in the tds? after being applied for 52 hrs it remains a soft tacky paste.**
A: Hello.  I use this product quite often. It holds very well, seals very well. I just put some on my differential fill plug and seals it great. To answer your question, this product, when first put on threaded hardware will be wet and soft and be able to seal low pressure and intermediate pressure. Parts can be readjusted, torqued, etcetera with in 24 hours of application. 72 hours just means it is fully cured and can withstand  higher pressures. But, once applied, it holds very well within hours. Definitely within 24 hours. It does not solidify, it stays wet and soft. It's good stuff. Hope this helped.

**Q: I was told i could use this on an oil pressure sending unit and seen on websites it could be used. so someone just told me I shouldn't. So can i?**
A: Yes, it works great. I use it on oil and brake system components exposed to high pressures and temperatures. No leaks, ever. Make sure it is applied to clean Dry threads. Use a solvent to clean threads, let dry, then apply the permatex. Be careful not to cross thread. Don't overtighten!! Cheers

**Q: Will this work on differential bolts that thread through into the case and are exposed to differential fluid?**
A: Hello Michal.  Yes this thread sealant does work on sealing differential fluid. I have used and know for sure it works  on sealing  the differential fill plug. If your referring to the cover bolts, you need a gasket or gasket maker to seal the cover. I'm not sure what bolts your referring to, but yes this sealant will seal differential fluid. Hope this helped.

### ⭐⭐⭐⭐⭐ Perfect high temperature thread sealant
*by J***S on October 12, 2025*

This thread sealant has never failed me. I used it about a year ago when I installed the coolant reroute onto the back of my Mazdaspeed miata engine. The sealant was used to install the hose barbs into the reroute itself. I also used this when I installed a coolant temperature sensor onto a coolant line on my Miata, this sealant was used on the probe that is screwed into the fitting on the line. The pictures are of the flyin miata coolant reroute and of the in line sensors both of which i used this thread sealant to screw in either the hose barbs into the reroute or the probe into the in line fitting. The sealant has performed flawlessly and never leaked.
