Met-L-Chek VP-31A | Visible Red Penetrant (1 Gallon)

High-Sensitivity Surface Flaw Detection for Critical Inspections

Met-L-Chek VP-31A is a high-performance, deep-red visible penetrant designed for the detection of surface-breaking discontinuities such as cracks, laps, porosity, and seams. Engineered for maximum "bleed-out" visibility, it provides an intense contrast against white developers, ensuring that even the finest defects are easily identified by the human eye.

Key Performance Features

• Exceptional Contrast: The deep red dye is formulated for high-definition "indications," making it easy for inspectors to distinguish flaws from the background.

• Dual Method Versatility: Fully qualified for Method B (Post-Emulsifiable) and Method C (Solvent Removable) processes, providing flexibility depending on your inspection environment and part geometry.

• High Sensitivity: Rated as a high-sensitivity penetrant, it is ideal for critical welds, castings, forgings, and general metal fabrication.

• Low Halogen & Sulfur: Formulated to meet the strict requirements of the nuclear and aerospace industries, ensuring it is safe for use on nickel-based alloys, titanium, and austenitic stainless steels.
