New J-B Weld FiberWeld Pipe Repair Cast 1" Kit 2.5Cm X 121Cm, Packaging May Vary

Did the job nicely, on a 5mm hole blown open in a copper pipe in an outhouse when I was away during freezing temperatures. You have to keep molding the putty onto and around the hole and pipe as it slowly hardens, as it doesn't seem to cling to the pipe for a while, but does so eventually as it hardens. The FiberWeld stuff on top of that is brilliant. I used it alone to repair a smaller leak in the same pipe a few years ago, and with the putty as well, this saved me a hundred quid or more to call out a plumber.

Worked an absolute treat. Had a leak on an old iron pipe that couldn't be replaced and having tried various repairs, this is the only one that really worked. Once in place, it goes harder than Chuck Norris

Works really well 👌 fixed our leaking pipe

Amazing stuff I had a leaking hot pipe under the bath repair man couldn’t get to us for a fortnight so I wrapped the pipe in this it held the whole fortnight an probably would of lasted longer it was that solid the repair man ended up having to saw the whole pipe off oops so does what it’s advertised to do I’d definitely buy again and it was cheaper than the local diy stores so I was really pleased

Fiddly to get a good repair on an uneven pipe but does set quickly.

Brilliant fixed our leak

Does the job well

I tried several other products to temporarily seal a leaking pipe near our radiator. This is so good it’s a permanent solution. Easy to use and sticks like you won’t believe. Fabulous product.

bien reçu

Expired more than 1 years ago, can’t use .

Product that I received looks like stored or transported incorrectly because one of the components (cold weld) has been activated and doesn’t mix properly with hands. Overall this kit not work as I expected.

The 2 part paste wouldn't mix properly it was crusty

This worked on cooper piping for the water line. I installed a water recirculation pump and it worked fine; however, it took a lot of cooper fittings and nipples to install it. Some of the copper fittings and nipples were not perfect, so after a few months one joint started leaking. Instead of redoing the entire pump installation, I was able to stop the leak using this epoxy - it worked great and appears to be a permanent fix. It was in a difficult area to access, too, but it took less than an hour to make the repair and another hour before re-pressurizing the pipes.
