Magnaflux Spot Check Kits

SK-816 Visible Red Dye Liquid Penetrant Kit for Convenient and Effective Testing

High Quality & Reliable 

Spot Check products are the most reliable and widely used penetrant inspection method that reveals cracks and other surface discontinuities in virtually any non-porous material. Spot Check's formulation, using a high concentration of quality dyes together with high quality solvents, provides the best possible dye penetrants for finding defects. Other products may skimp on dyes or use inferior solvents that cut costs. In doing so, indications do not appear as bright or vibrant and cracks can be missed. Some inferior solvents may also cause health hazards. Our developer's even spray pattern provides a uniform coating.


SK-816 Visible Red Dye Liquid Penetrant Kit

The SK-816 Kit is a convenient collection of Magnaflux dye penetrant testing consumable products in easy-to-use aerosol form for Type 2 penetrant non-destructive testing. Each penetrant testing kit comes with SKL-SP2 solvent removable penetrant, SKD-S2 solvent-based developer, and SKC-S remover. No ultraviolet black lights are required and the kit includes everything needed to perform visible red dye liquid penetrant inspections. SK-816 Kits come in a plastic carrying case making them portable and great for job sites or field inspections to check welds, forgings, pressure vessels, castings, general metal work and many other applications.
