Loctite2087067 567 Thread Sealant 50 mL Tube, White (Pack of 1)

The gold standard for liquid pipe thread sealant. When PTFE tape just won't seal it (and you are willing to wait a few hours for it to fully cure/seal), hard to beat the Loctite product.

Had to use this on numerous 1" SS joints and it worked perfectly. I made a test joint and it was rock solid. Part of the test included loosening the cured joint which required a cheater extension on the wrench but I was able to get the joint apart... there was no galling. Isopropl worked very well to remove excess uncured and cured sealer.

Great stuff!

I have a MR5 water purifier and this is the only glue I could use to repair it.

Works well, Be sure to kneed the tube before use as it separates in storage.

Sealed NPT threads on an automotive fuel line, with no leaks. Before, when I didn't use the sealer, I had seepage.

This was great .They had the part that I needed and With prime the shipping was free and fast !!

Best general purpose pipe sealant. Use it for most everything except steam. Only because there are better products for steam.
