Can you use this to seal a leak/hole in a copper/steel pipe under water pressure? Any secrets to making a good seal? Is this a permanent seal? Thanks

Yes you can. See this video from Youtube. This is how I fixed my leak successfully. https://www.youtube.com/watch?v=IRpkklLqoKI

Yes, 1/4" NPT - use brass (nonsupplied with unit) - not aluminum or steel, with a thin coat of teflon sealant on the male section. Be sure sure to arrainge it so the face, which is small, is at a angle that you can read when finally tightened. Have had mine for apx 18 months and it still does not leak-down in-between uses of 2 weeks max at temps from 20f to 120f. I would buy this over many others, really good unit. - Baker

I don't think so. Where is the leak and what kind of leak is it? I was not impressed. If the leak is under water, i think under-water epoxy is the best joce. It is used on swimming pools and I used it on a leaking pool light connector. It worked great.

It's tape. It's not permanent. It is an aid in dealing with air leaks-whether cold or hot in situations in which it may not be practical or affordable to structurally fix the opening. Eventually all tape will "weather" and you may have to peel or scrape it off.

this does not have U.S. pipe sizes. I believe they are 20mm which is larger than 1/2" pipe. Therefore it's difficult to get a good seal. Epoxy will work or I've used teflon paste and layers of tape and it worked.

I think to a certain degree you can use it for that purpose. If its a very important pipe i would avoid using it. However, if you use enough tape and make it tight, I imagine you can indeed fix a leak. I am sure it depends on the amount of water pressure and environment where the leak is.

For a metal awning use Black jack metal roof sealant. It will plug any small leaks as well as water proof your awning and also help keep the underside cooler.Thompson Water Seal is for wood. And does an excellent job for wood like porches or decks. I've used both products.

I used these for striped valve cover threads on an aluminum head. I do not have any leaks to date.

This product is specifically for Roots that are growing into your pipes. This is more typical with the OLD STYLE Piping (1930's-1960's). It won't unclog a drain if its due to hair,grease,etc.The Copper somewhat kills the roots back causing them to shrink & retract. If you notice the problem is more prominent in Sept.-Oct(First rain) through April then you have a Root issue.

I only used it while snorkeling and riding a jet ski. When sealed properly it was perfect in those conditions. Perhaps you should contact the manufacturer with your question, because I do not know how water pressure during diving would affect the seal.

doubtful. this stuff only works for a short time, then the leak will re-develop. Especially, if leak is at an increased pressure point.

We used it on the outside of our hot tub cover as it was tearing along the seam this past winter. Here in MASS our winter was harsh. The tape held up all winter. We replaced our cover in the spring so it did what we wanted. My husband is a plumber and said it should be fine on a drain pipe but nothing with pressure. It is water proof .Hope this helps

My educated guess only: as a retired engineer and not a product specialist for this Glue. Based of my usage of this product if you sew your sole by applying this glue (before glue dries and apply some more as sealant on the thread after sewing. It might serve as water proofing I believe the glue would prevent water to pass through in short period of time. Long term I don't know. Best to call Aleene's company, thier phone # (800) 438-6226 and ask them. We do that all the time as an application Engineer. They should know the capability of their product - hope this helps

I guess that would depend on the application... it is not a traditional thread sealant and it should not be used with a water supply line that is under pressure... pretty much just for drain lines. The most common use is between the sink and sink drain or garbage disposal... you make a rope of it, lay it around the top surface of a new or cleaned old sink, you then put the drain in, you install the washer and tightening nut from below the sink and tighten it slowly... allowing the putty to flatten out, seat and seal. Continue to tighten a little more until the putty stops settling.

Hi Pressure lines have Steel Cords weaved into the hose and I would not recommend using just a seal covering to do any more than get me to the next service station, as a fix. The Silicone sealer does work well, for Low Pressure applications though, or keeping water out of a splice etc.

I think you could use it as a temporary fix for a hole in a pressure hose. Make sure the hose is clean before you apply it. I used it for a drain hose just fine, but there was no pressure in the hose. There is some flexibility but it is a thicker tape, so it's not going to be like regular duck tape.

I've been doing maintenance for 32 years and my experience is that if there is no foreign object in the hole, the threads are not noticeably damaged and you can tighten the pipe into the hole (with teflon tape or pipe dope on the threads), it should not leak. Would not hurt to chase the threads in the pump with a small steel wire brush.
