Two Steps to Stop a Leak
- Drill a uniform hole at the point where the leak originates.
- Tighten the plug into the hole with a hex or socket wrench. The self-tapping threads cut their own path for an immediate seal.
Welding the plug in place is an option at the operator's discretion. For heat exchanger tubes, puncture the tube first with the One-Rev Internal Tube Cutter so pressure can't build up behind the plug.
