Temperature range from -65 degrees fahrenheit to 400 degrees fahrenheit.

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.

### ⭐⭐⭐⭐⭐ 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.
