The Cadmium Plated Steel pipe clamps are designed for temporary repairs only. This clamp should never be used to make repairs on any lines containing flammable materials, potable water or low to medium air should be the only items within the line being temporarily repaired. These clamps are not recognized by any building official as an approved pipe repair. It is very rare that a leak is isolated to only one section of a pipe and because of this, you should have a professional plumber assess the integrity of your piping system.
