Review on πŸ”§ J-B Weld 8277 WaterWeld Epoxy Putty Stick: Versatile 2 Oz. Repair Solution by David Jennings

Revainrating 1 out of 5

Will not repair a pinhole leak in copper tubing when water is present.

Perfect execution of instructions. THIS DOES NOT STUCK to bare/grounded copper to hold the pipe. I used half the tube and it started leaking immediately and after 24 hours. It's far better to just take a piece of rubber hose and tighten the clamp around the leak. I can't imagine this working in the wet at all. Period. Terrible.

Pros
  • ORIGINAL COLD WELD by JB Weld was developed as an alternative to torch welding. Engineered to work effectively in extreme conditions, once hardened it creates a strong bond, stronger than steel.
Cons
  • Low maintainability
