• Big Blu SubZero is the most durable product of its kind for leak detecting under extreme conditions
• Bubbles and foam will keep regenerating where other low temp products give out, freeze or become gelatinous
• SubZero 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
• Non-toxic, non-corrosive, biodegradable, oxygen safe
• The original Big Blu family of bubble leak detectors are used by OEMs and industry professionals worldwide
• This is the only bubble/foam solution capable of detecting gas leakage down to 0.65 oz per year, use on any gas including oxygen
