Nu-Calgon Cal-Blue Plus is a high-viscosity leak detection formula for refrigerant, natural gas, and oxygen lines, packaged in a 1-quart trigger spray bottle. Its thick, long-lasting bubble formation clings to fittings and joints, revealing even the smallest leaks, and it will not interfere with UV/blacklight dye detection methods. Rated for use from 5°F to 225°F, it is non-corrosive to metal and safe on copper, brass, and steel HVAC components.
