- Functions:Dye
- Applicable Processes:Leak Detection
WATER-GLO® ULTRA SPI-WGB-55G is a fluorescent leak detection dye for use in industrial water-based fluid systems. It quickly finds leaks in closed loop systems containing fluids that are miscible with water, glycol or similar fluids, such as boilers, hydronic heaters, pumps, sprinkler systems, storage tanks, pipes and associated fittings. For best leak detection results, use WATER-GLO® ULTRA dye with a Spectroline® inspection lamp in low-light conditions. SPI-WGB works only with ultraviolet light.
