Leak Detector Liquid for HVAC Systems

Hercules 45802 is a blue, non-corrosive leak detector liquid supplied in a 32 oz container. It produces long-lasting bubbles that cling to vertical surfaces, helping technicians locate even the smallest gas leaks in air conditioning and refrigeration systems. The non-toxic formula is safe to handle during routine maintenance and installation work.

Ideal for HVAC Technicians and Installers

This product suits professionals who need a visible, bubble-based method for pinpointing refrigerant or gas escapes on piping, fittings and coils. It is not intended for electronic sensor-based detection, tracer-gas workflows or automated monitoring systems. Buyers requiring a digital leak detector, UV dye kit or a formula certified for oxygen service should look at alternative solutions.
