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.

This Megaloc Multi-Purpose Thread Sealant is a great general purpose thread sealant. I am a DIYer on just about everything around the house and have found this product to be a real time-saver and insurance policy against leaks. I use it on all threaded joints where Teflon tape or pipe dope would normally be used and so far haven't had any leaks. On some time-consuming or difficult projects where a leak would be a major issue, I have used Teflon tape followed by Megaloc thread sealant just to be sure leaks don't develop. And it cleans up much easier than the old gooey pope dope – just wipe it off your hands with a rag. Recommended product for the professional or DIYer.

I picked this up to seal joints in a 1 inch black pipe gas line going into a new building. Megaloc is pretty much an all purpose thread sealant. I did not see any everyday applications where this could not be used. There are some exclusions -concentrated acids and alkalies, keytones and oxygen lines. I have used a lot of different thread sealants in a lot of different applications over the years - pipe dope, teflon tape, and horse hair (yep). For a lot of plumbing, teflon is my go to - even the yellow teflon tape for small gas connections. But for black pipe, especiall for anything lager than 1/2 inch it's pipe dope. Megaloc has a couple of advantages over other pipe dope thread sealants. First, working with pipe dope tends to get messy no matter how careful you are. Typically you are dipping into a can with a stick and smearing the dope onto the pipe threads. Some of the pipe dope ends up in a place you didn't intend to put it, or you drop the stick or someone steps on it and gets pipe dope in even more places you dont want it. The in-cap aplicator brush might seem trival but is a godsend for keeping things neat. Even if you are super careful chances are you are going to get pipe dope on your hands or on your wrenches. When that happend in the past, it seemed like sticky pipe dope would just follow you around - and it was a real pain to clean up. Which leads to a second advantage - with Megaloc you simply wipe off any misplaced or excess sealant with a paper towel. It really is that easy. I was skeptical so I got a paper towel and stuck my finger in the can - wiped right off! Try that with any other pipe dope. [This review was collected as part of a promotion.]

Application is very straightforward - just brush on. You also dont have to wait for it to dry - just screw the joint together afterward. It's nice not having to mess with wrapping tape or applying from a tube and needing to use a finger to get it around the pipe. This simplifies all that. Plus the paste wipes with a dry rag - don't need a solvent or anything. It also does not have a strong odor (smells similar to plumbers putty). A nice product to have in the toolbox.

This is a high performance multi-purpose, non-drip, soft set thread sealant with an application brush in the cap.

Leak-proof hydraulic resistance to 12,000 psi. Performs over a temperature range of -50ºto 400ºF (on steel pipe). Not recommended for lines carrying concentrated acids, alkalis, ketones and oxygen. It wipes off hands with a dry cloth. Finished joints can be tested and put into service immediately. [This review was collected as part of a promotion.]

I was concerned that the extremely cold weather may have affected it during shipping. I have been working on a Bathroom RENO with some plumbing projects included. I used the MEGALOC to replace some plumbers tape on a new shower head being installed. The installation went smoothly and the excess sealant cleaned up easily. Just brush it on the threads and make your connections.You don't have to be concerned about which direction to wrap the 'TAPE' or how much to apply. This is my first experience using this sealant. I anticipate that everything will be just fine. The sealant did not harden as some products I've used and it is rated for both high and low pressures. Any repairs in the future should be easier than having to dig the tape off the male and female threads. I would recommend any DIYer to give it a try.
