01-5155-78 - Miller SKL-SP2 Spotcheck Red Dye Penetrant, 16 oz Aerosol (Pack of 12)

High-Performance NDT Inspection

The Miller SKL-SP2 Penetrant (01-5155-78) is a premium solvent-removable, visible red dye penetrant designed for critical non-destructive testing (NDT) applications. Supplied in a convenient case of twelve 16 oz aerosol cans, this product is engineered to locate surface-breaking discontinuities with exceptional sensitivity. As a Type 2, Method C penetrant, SKL-SP2 utilizes strong capillary action to migrate into tight cracks, laps, and porosity, ensuring that even microscopic defects are identified during the inspection process.

This penetrant is formulated to produce vivid, deep red indications that contrast sharply against a white developer background, minimizing the risk of missed defects. It is widely recognized for its reliability in industrial environments and meets a comprehensive list of industry specifications, including QPL-AMS-2644, ASTM E1417, ASME, and ISO 3452. This makes it an ideal choice for certified inspectors working in aerospace, nuclear, and heavy manufacturing sectors where adherence to strict quality control standards is mandatory.

The solvent-removable nature of SKL-SP2 allows for excess penetrant to be easily wiped away with a solvent cleaner/remover without washing out the penetrant trapped within the defects. This controlled removal process enhances the definition of indications and reduces the likelihood of false positives. Whether inspecting complex castings, forgings, or machined parts, this penetrant delivers consistent, high-grade performance essential for maintaining structural integrity and safety.
