There are limitations on even the best “bubble solutions” used for “leak testing. My favorite is SNOOPS, and as I indicated in the title, even it has limitations. There are two (2) different types of SNOOPS:
- Snoop Liquid Leak Detector
- Real Cool Snoop Liquid Leak Detector
Snoop Liquid Leak Detector
Nontoxic formula
Composition: Deionized water and a surfactant.
Temperature rating: Can be used over a temperature range of 27 to 200°F (–2 to 93°C).
Real Cool Snoop Liquid Leak Detector
Works at temperatures as low as –65°F (–54°C), even on very small leaks and vertical surfaces.
Composition: Deionized water, a surfactant, and ethylene glycol to prevent freezing at low temperatures.
Temperature rating: Can be used over a temperature range of –65 to 200°F (–54 to 93°C)
