Many cracks that extend to the surface of metal parts are completely invisible to the naked eye. This is because they may not open up to a visible size except when subjected to operating stresses or high temperature. Yet, these small invisible cracks can continue to grow until they fail catastrophically.

This quality dye penetrant system can make many of these small cracks visible because the very low viscosity penetrating dye wicks into the tiniest of cracks. Later, when the developer is applied, the dye bleeds out of the crack making it clearly visible under UV light (blacklight). This handy, low cost system allows you to perform these tests yourself. Kit includes one can each of UV Penetrant Dye, Cleaner/Remover, and Developer -- enough for up to 500 small scale tests. Requires a blacklight (365nm recommended) such as our Ultraviolet Inspection Flashlight, Part No. 3786-004 (sold separately).

Replacement cans of each component are also available separately: The Crack Testing Fluorescent UV Dye, the Crack Testing Cleaner / Remover, and the Crack Testing UV Developer.
