how long should JB Weld 8277 cure before water pressure can be applied to a copper connection?
1835331
the instructions say right away but I generally like to let cure for at least a few hours.

We usually wiat a good 12 to 24 hours. The longer you can hold off the better. We also put a portable fan on it for drying.

While the instructions clearly state WW sets-up in 20 minutes, and becomes "functional" in 60 minutes, the data sheet that comes with it states, though not as clearly, its full set (cure) time is 24 hours. This is a standard with most glues, epoxies, and adhesives, even when it states less time is needed. However, when more time is stated, abide by that time. MY EXPERIENCE: Nearly 30 years in the retail and wholesale hardware industry.

Probably 24 hours. I was never able to get the JB Weld to stop my leak. I used the entire tube and the small leak that I have is still dripping.

Not easy; I used a very small copper wire to fish it thru. Thread might led it thru.

I dont have any experience joining 2 dissimilar materials with JB Weld. Sure did work great on my plastic top Nissan radiator. Still is working great.

I haven't actually installed my rain chain yet. I bought some special coating to apply so that the copper stays bright, and I haven't had time to polish the chain and apply the coating yet. Also, we have vinyl rain gutters... so there is not an issue of two metals causing corrosion.

yes it will but you will need to turn the temp down to 1. Change the heat setting to match the material. Additionally I have not changed the wire speed once it has been dialed in to the material that is being welded..

Crimped connection done right will be physically stronger and gas-tight. Soldered connection has the hazard of wicking into stranded wire, making it brittle. Use anti-corrosion silicone grease and heat shrink tubing if you can.

Schedule 80 PVS would be a gamble in my opinion, rated at 21 to 1200PSI. If your application is high pressure I would not trust the welds. I maybe wrong. My experiences are uses not under high pressure conditions. Not sure if this helped you or not. Best applications seems to be automotive body work.

1/2" National Pipe Thread (NPT). Teflon tape must be used on threads. To avoid corrosion, thread only into a Copper female fitting, not iron.

I purchased Ameriflame to braze copper, but it has performed well in light welding. It has completely satisfiedall my brazing and welding needs. Good Luck

I have used JB weld and for some repairs like he mentioned but you have to use more than the thin film that fills the crackin the line of fracture.fFirst stick it togetherand thenleave it set then put a donut of the material around the break then smooth it out with a dremel smoothstone. WJD

I think it will. The only problem I see is the heat. JB Weld has held up to everything else I have thrown at it. Balancing its small cost against the risk of failure, my advice is to try it. The worst that can happen is that it doesn't work but you still have partial tubes of the stuff for the future. It is always handy to have around!

Clean ALL leads of any debris, wipe with denatured alcohol. Wires, connectors everything. Check for cracks in insulation.If u do wrap this copper tape around it, be sure to ground the tape.Good luck.

Yes. Make sure the copper paint is dry. Then use a clear polymer spray sealant that is waterproof and permanent. Spray several coats making sure they dry completely before spraying another coat. Let dry well before handling.

Yes. Turn off water, let area dry, roughen area with sandpaper or steel wool, then press the Water Weld into the area of the leak.

It was worth a try. This JB Weld is some great stuff. If the handle is hollow on the inside. I would first scuff up the area, then apply some extra to the inside to give that area some extra support. And, put a little extra on the out side. Let it cure for the full time before using it. It ends up with a nice shiny grey finish, when cured all the way. It can be applied in multiple layers. It does like to run, if applied too heavy. I used it to replace the four corners of an aluminum screen window. It originally had the 4 plastic corner supports that fell apart on me. It is now stronger, then it was when new. I was very happy with the results. Good luck !! It was worth a try. This JB Weld is some great stuff. If the handle is hollow on the inside.

I think it's a heat connection. Not welded. I can't speak to glue, but I have run it through the dishwasher many times with no problems.

I'm no expert , but...my attempt to fix a pin hole leak in a copper pipe (not under water) did not work because this repair tape is an open mesh and, even when set, would not stop water coming through. I'd try another option first.
