The Rocol Flawfinder Crack Detection System Kit is a professional non-destructive inspection system designed to reveal surface cracks and flaws invisible to the naked eye. This three-part dye penetrant testing system provides tradespeople and engineers with a fast, reliable method for quality control and safety inspections across metalwork applications. Ideal for inspecting welded joints, castings, and forgings, this complete detection system identifies hairline cracks, porosity, and surface defects that could compromise structural integrity. The kit delivers a comprehensive NDT solution for maintenance engineers, welders, and fabricators working in manufacturing, aerospace, automotive, and general engineering environments. The system comprises three essential components that work together to detect surface discontinuities: a 300ml cleaner spray to prepare the test surface, a 300ml dye penetrant that seeps into cracks, and a 400ml developer spray that draws out the penetrant to create
