VIPER Big Blu Sub Zero Bubble Leak Detector - 1 L


The Big Blu range of bubble leak detectors is used by OEMs and industry professionals worldwide. With a temperature rating of -34°C to +95°C and capable of detecting micro gas leakage down to just 22.4 grams per year, Big Blu Sub Zero is the most durable product of its kind for leak detecting under extreme conditions. Where other low temp products give out, freeze or become gelatinous, Big Blu Sub Zero keeps regenerating bubbles and foam and the product maintains a uniform viscosity over this temperature range, remaining fluid on the coldest of days while remaining bulky and resistant to evaporation on hot discharge lines.
