For finding the most elusive gas leaks in high-stress environments, Big Blu RT100S High Temp Leak Reactant is the industry standard. This 1-quart spray is a proprietary viscoelastic liquid engineered to detect micro-leaks as small as 0.65 oz/year. Unlike standard soap bubbles that pop or dry out, this bubble leak detector creates a persistent, high-output foam "cocoon" that stays visible for up to two hours, giving you ample time to identify the source of the discharge on large equipment or complex pipe runs. Rated for temperatures ranging from 27°F to 200°F, the Big Blu leak detector is indispensable for troubleshooting high-side refrigeration lines, discharge headers, and industrial gas systems. It is non-corrosive, non-toxic, and NSF P1 certified, making it safe for use in food processing facilities. The formula is also oxygen safe, meeting MIL-PRF-25567 standards, and does not contain chlorine or aliphatic amines that can damage sensitive alloys. For HVAC leak detection that requires precision on micro-fissures, this refrigerant leak reactant delivers the field-tested reliability needed to reduce call-backs and keep systems compliant. Key Benefits: Extreme Sensitivity: Detects micro-gas leaks down to 0.65 oz per year, magnifying them into visible foam clusters. High-Temperature Stability: Maintains film strength and visibility in environments up to 200°F (93°C). Universal Gas Compatibility: Safe for use with all gases, including high-pressure oxygen and natural gas. Material Protection: Non-corrosive aqueous solution that is gentle on metals, plastics, and composite materials. Professional Compliance: NSF certified for food-safe zones and biodegradable for easy cleanup. Common Questions: Can this be used on oxygen lines? Yes, the RT100S is formulated to be oxygen safe and conforms to MIL-PRF-25567 specifications for oxygen systems. How long will the foam remain visible? The viscoelastic formula is designed to preserve foam "cocoons" for up to two hours, even in vibrating or high-airflow environments. Is it safe for kitchen grease or food-prep areas? Yes, the NSF P1 registration allows for safe application in and around food processing and handling equipment. This item is not eligible for free shipping.
