Would this work to seal a crack in an aluminum RV hot water tank that reaches about 140 degrees F with a maximum pressure of about 60psi???

I doubt it. This is made to seal small pinhole type leaks, which it works well for. Cracks in metal flex with pressure and temperature and the crack will very quickly reappear. Could be a safety issue as well. If the tank can rupture due to the crack the sealant will not stop it. A good certified welder may be able to fix it right, but cracks are very hard to fix at the best. Go by the welder's judgment who will probably suggest to get a new or good condition used tank.

My guess it would handle the temp. I cured my fuel tank at 140` but i dont think it would handle the pressure if there is any flex to the tank at all. This is an epoxy that dries solid. Just my 2 cents.

I think so. I used it to add water to my water bed, and ran mostly hot water from the tap through this hose to the water bed (since I didn't want the bed to take a dozen hours to get warm enough to sleep in). The hose handled it fine. I can't say the water got up to 140 degrees for sure, but it was well over 100 degrees. Hope this answers your question.

I would be a little wary of such an application, but you are in the best position to make the judgement call. Is the place you wish to apply the insulation warm or hot from the proximity of the flame? If so, that would concern me. I would not be concerned if the heat is merely from the hot water in the pipe -- insulating that is what this tape is for. The insulation is plastic and might possibly melt, or even burn if exposed to a flame, however. I would think that this is something you would not want to take a chance on.

Well the specs do call for water sealing, however, I find teflon tape is a better way to go unless the threads have been cross threaded. Good luck.

I don't think so, there has to be coolant circulation there to carry the sealer. it will probably need welding. I've heard of epoxy brands than can patch external cracks with a piece of tin. it probably depends on the severity & location.

i doubt it- the hose would squish in when you try to snug the tape down. if you used this to cover one of those metal 'hose repair fittings ' that always leak it would likely seal. It didnt seal a leaky pipe joint on a hot water boiler line - just dripped out around it. Good luck

It works best if not allowed to get too hot. I use it to heat large tanks, It must be very well attached to a good conductor of heat. I use Silicone RTV Red, and I also wrap the bank side with aluminum and clamp it down firmly.

I used this on a 15 year old 1200cc 4 cylinder which had an uneven lowerblock, and I had tried ceiling the leak with high temperature silicone,with nosuccess. The Bar Leaks Gasket reduced the leakage by about 60%, and was finefor short trips that did not require full power, but on hilly roads, the seal blew out.I believe that the silicone sealer prevented the Bar leaks from bonding properly.I replaced the engine.

If your leak is in the copper heating core, then I don't think this would the right product for that. This is for fixing plastic. See their website or call the manufacturer to be sure.

Depends, I used it for dryer duct sealing (inside and out) but that only gets so hot...i.e. this is not to be used on ovens as that temperature will be too hot for this tape. Check what your heat pump temps will be where you want to use this. This tape is rated for -10 to 180 degrees. So if your spot where you're using this doesn't exceed 180, this tape works awesome !

Yes it would as the silicone in it would prevent any water from getting in , also depends how big your Crack is .

I don't see why it wouldn't. Mine has sealed everything I've tried that as long as it's a plastic type of material.

The pump was not made for water of this degree, so yes it would, but it would not last for a long time. The pump was made for water at normal temperatures without the extremes. 120* F should be a MAX on the Temp.

It should create an effective seal on most materials. My application was on a ceramic and cast iron sink.

This product is pretty "stiff" under normal conditions, and is therefore very limited on bend radius - you can not form it into a tight bend without kinking it. It needs only a push-on barbed irrigation connection to work fine at pressures of at least 30 psi in my hookup. Since you plan to run heated water thru it, it will be much more "limp" and may need to be fastened at every connection with a hose clamp. With that precaution, and keeping in mind the bend limitations, I see no reason why it should not work.

I would not recommend using it on a radiator hose as the pressure and heat will probably cause the seal to break, but I have not used it on a rubber based item. It tends to work better on plastic or hard (metal) materials, making a better seal that tends to hold. It is no magic remedy.

I tried to use it to seal plexiglass to sheet metal and it did not work at all. It may work for your application.
