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.

Questions about this item
Will the 1 qt bottle of Cal Blue LT need to be replaced after a certain number of leak checks?
The 1 qt container provides enough high-viscosity formula for many inspections; replace it when the liquid runs low or if it has been stored beyond the manufacturer's recommended shelf life.
What temperature limit stops the detector from forming bubbles during a long job in a hot attic?
The formula is rated up to 220 °F, so sustained ambient heat above that point will prevent reliable bubble formation.
Does the blue liquid give off fumes or heat when left on pipe joints all day?
The non-corrosive, advanced formula produces no significant fumes or heat and remains stable on the applied surface for an extended period.
