Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Best Pipe Dope Ever This pipe dope is awesome. I had trouble sealing some threads made of galvanized steel with PTFE tape, but it leaked with 125 psi air. I was building an air gun with some galvanized pipe, so I used this dope and it has no leaks! November 2, 2014
Rated 5.0 out of 5.0 by The ultimate pipe dope 90% of the time you won't need a product this good. Cheaper pipe dope works great most of the time. This product however actually seals up poorly threaded pipe and used or beat up threads. If you are repairing/ fixing some piping and want the very best pipe dope, get some. I was installing a flared filter/drier on a refrigeration unit that vibrates badly. I could tell just by the consistency of this that it was going to work well. I usually just hit my flared fittings with a little refrigeration oil and tighten them up. But in this case I wanted something more like an adhesive to lock the flare nuts in place. October 6, 2014
