Urethane Supply High Density Polyethylene (HDPE) Plastic Welding Rod, 1/8" diameter, 30 ft, Natural

I never knew you could solder plastic. I have a wheel barrel that’s made out of plastic, which had a crack in it. It was holding up, but I didn’t want the crack to increase. I use this plastic rod and a soldering iron and solder the crack. It sealed it up great and have used the wheelbarrow for hauling logs and it still holds.

The product is easy to use

Had to repair a butchered plastic fuel tank outlet on an ‘88 Porsche 944. I don’t know what happened to it or what part of what was there was someone’s idea of a repair. Either way, it leaked gasoline and was a disaster waiting to happen. With these and a Harbor Freight hot air welder, I recreated a suitable sealing surface and mitigated the leak. So far so good!

Actually had to use this to repair plastics on my quad, works will with Harbor Freight plastic welding kit and a heat gun. I actually had to fill in some big support holes with stainless screen and his stuff, works well on high stress areas. Wish I discovered plastic welding 30 years ago.

If you need a really clean joint, this probably isn't your product, but it does seem to make the joint stronger. I ended up having to clean it up with a Dremel tool. So if strength is your priority, this is good stuff. If you need pretty, or a sharp corner, take another route perhaps?
