          This is a great sealant for all types of piping. I just used this to get a great seal on the hard airline piping routed through for my workshop with numerous outlets. One can lasted the whole job and can do many more joints. This also works well on plumbing gas lines, electrical conduit that must remain water tight, etc. It also helps lube the threads when attaching new pipe as well and keeps it from rusting together while sealing tight. The applicator brush in the cap makes it simple and easy to use. No fuss and no mess. I use this sealer often and will continue to do so. I recommend it.

          I have been using Megaloc for quite some time now in an industry setting. We have used it on threads from 1/8th inch to 4 inches without any issues or leaks. I really like that when you mix the product the first time it seems to stay mixed well for the duration of the can. The problem we have had with other brands is that they dry out in the high heat conditions that we work in, not Megaloc.

          Bad for water connections.
          If you like doing your (water) plumbing twice, then use this product. 4 out of 4 properly torqued NPT threads will just drip water slowly. Ended up removing this junk and redoing it with traditional Teflon tape This might only work for gas lines? It's way too thin for water and end up getting washed away.
