Nu-Calgon 4183-24 Leak Detector 1 qt Blue air treatment

HVAC leak detector for technicians

The Nu-Calgon 4183-24 Cal Blue LT is a high-viscosity gas leak detector formulated for HVAC professionals. Its advanced formula creates long-lasting bubbles that cling to surfaces for extended inspection periods. The fluid operates across a temperature range of -20 to 220 degrees Fahrenheit. It is non-corrosive to metal, protecting piping and fittings during use.

Blue fluid properties for inspection

The blue colour provides clear visual contrast against pipework when searching for escaping gas. High viscosity ensures the liquid stays in place on vertical or overhead runs without dripping away. Because the formula does not affect ultraviolet or black lights, technicians can combine it with UV inspection methods. The one-quart container supplies enough volume for multiple service calls.

Compatibility checks before ordering

Verify that the system materials are compatible with a liquid leak detector before application. Confirm the operating temperature of the equipment falls within the stated -20 to 220 degree Fahrenheit range. Ensure local regulations permit the use of bubble-type leak detection fluids on the specific refrigerant type. The product ships as a single one-quart bottle.
