I use this thread sealant for my fuel cut off valves that I installed on my aqua hot heater on my RV. No leaks works really good. Great product.

Easy

This seems to work really well I had to install a gas line and I was reluctant to just use the tape so I added this as well and no leaks. The bottle is a little smaller than I had expected but it’s a great amount and I’ll never use it up.

Used this to fix my air compressor. The 3-port one way valve on the 50 gallon tank had failed, seized in place, brass into steel tank. Really tore up the threads removing it, had to re-tap it with a Chinese tapered tap in the steel bung. All that said, the "new" threads were not great - really rough. This Rectorseal product filled in the imperfections and sealed perfectly. Tank has been holding 95 psi for 24 hours so far. I did apply to both the inside threads on the steel AND the threads on the brass, but it worked and helped me save a >$300 compressor. AND I have plenty left for other uses. I think I will use this in places I normally would have used Teflon tape.

Price is unbeatable. Comes with plenty for what I needed it for which was a Blackstone grill. the color also makes a very easy to see. No issues with application.

Excellent stuff. Not for use on PVC or CPVC. This is good on brass gas lines, etc. If looking for a more general purpose, go with the white tube, not the yellow one. I tape first, then place a coat of this on top of the tape.

This stuff is awesome. For propane or water, Seals on the first try every time!

I needed to seal a gas line in our house after a fitting change and I won't cut corners where my family's safety is concerned . Ordered it up, used it as directed, tested for leaks and all was good! there's not much more I could tell you about it other than it effectively sealed the pipe joint where it counts! Recommended!
