Automobile plumbing. I need to ground an automotive electrical connection - for an oil temperature gauge - through brass and steel fittings. AutoMeter told me to avoid teflon tape, because it has insulating properties. Two questions. 1. Does this product have any insulating properties? 2. Will the hot motor oil partially dissolve the product, with the possibility that small pieces of it clog small oil passages in the engine?
Asked by: hmaynord
This is petroleum based product, there is a chance motor oil could break it down it may get into the oil curcuit. I don’t think this would give you a good ground. Try copper antisieze.

I have used this product and have found it not to perform up to my expectations with regards to a variety of different pipe threads. I tried it after having some problems, and also dealing with the mess of blue block. I have found Numerous leaks in foreign steel fittings using this product alone. I have also found numerous leaks using this product alone with old steel fittings. The leaks caused me to use a different product. I'm trying blue monster now and the modern equivalent of old fashioned lamp wick for non-drinking applications. It appears Home Depot does not sell blue monster. I did this review only because all the others are compensated reviews. Mine is a non- compensated actual experience review.

While the price may initially seem high, consider how much you would have to spend on teflon tape to equal the number of connections that a can of this can do. And, this thread lock stays put on the threads unlike teflon tape which tears and separates from the threads, requiring reapplication. This thread lock is easier to apply, can be used on potable water connections, compressed air connections and is easy to clean up.

Megaloc is up there in my top 3. Once we mixed the can for the first time it has not separated itself like others do. We work in a high temperature area which seems to dry out any chemicals in a couple of days, so far this product is still the same as when we opened the can. This pipe sealant will be welcome in my toolbox.

Rated 5 out of 5 by from This Megaloc Multi-Purpose Thread Sealant is a great choice for any type of project where you need to thread fittings together. I have found it to work great on everything from oil furnace lines, natural gas lines, air line fittings and of course hot and cold water pipe. I like the consistency of the material as it does not drip or make a mess. It leaves a nice coating on the end of the threads and does not dry out or crack. You do not need pipe tape with this thread sealer but I know many plumbers that use both to be extra safe, they also wear suspenders and a belt. This 16 oz. can is a great size for the price and has a built in brush to make a easy application.

Goodreads really good product works on the threads of lubricate and let them seal properly so that they do not leak works on water gas anything that you need to have a sealer on the thread recommended for DIY users along with professionals product is relatively easy to use you unscrew the lid with the brush on the inside placeable to see what the threads and then tighten them up would recommend.

I have a big project coming up. I am replacing my 40 gallon water heater with a tankless water heater. I will use this thread sealant on all threaded pipe connections, water and gas. It is NSF rated so it can be used on all drinking water lines. No need for teflon tape. This stuff makes leak-free threaded joints on metal and plastic pipe including gas lines. It will not harden, crack or become brittle. Has a zero wait time. Has a built-in applicator brush. Very easy to use and has a medium consistency and stays where you put it. Wipes off your hands with a dry rag.
