Rectorseal 1.75 Oz No. 5 Pipe Thread Sealant 25790

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

Works well on my pipe. Great sealant and holds the pipes well without leaks

Needed to wait an hour for curing time, otherwise after a few minutes it didn't create a strong enough seal on the threads to stop the slow leak. I wish they just stated this in the instructions, I had to find out searching google. They want to sell it as if it works immediately, but I don't see that being realistic based on my experience.

Used this for connecting our gas stove. Followed the directions and have had no issues. Great product.

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.
