MET-L-CHEK FP-923 Bulk Fluorescent Water Washable Penetrant (Level 3, PMC 4360 Qualified) - 5 Gallon Pail

The MET-L-CHEK FP-923 is a premium, Level 3 high-sensitivity fluorescent penetrant, specifically formulated for the water washable (Method A) process of Liquid Penetrant Inspection (LPI). Supplied in a robust 5-gallon (18.9 Liter) pail, FP-923 stands out due to its qualification to the rigorous Pratt & Whitney PMC 4360 specification, making it a preferred choice for aerospace and other critical applications where stringent material compatibility and superior crack detection are paramount.

Key Features & Benefits:

• Ultra-High Sensitivity (Level 3): As an AMS-2644 Level 3 penetrant, FP-923 offers exceptional sensitivity for detecting even the most minute and tight surface-breaking discontinuities, such as fatigue cracks, stress corrosion cracks, grinding cracks, and porosity, crucial for high-integrity components.

• Fluorescent Indication: When exposed to UV-A (black) light, indications fluoresce with a brilliant yellow-green color, providing outstanding contrast and clarity against a dark background, ensuring reliable defect identification.

• Water Washable (Method A): Excess penetrant is easily removed from the test surface using a simple water rinse. This method is efficient, economical, and suitable for high-volume inspection environments and complex part geometries.

• Pratt & Whitney PMC 4360 Qualification: This critical approval signifies that FP-923 meets the extremely demanding material property requirements set by Pratt & Whitney for use on aerospace engine components. This includes very low levels of halogens (chlorine, fluorine) and sulfur, ensuring it is safe for use on sensitive alloys (e.g., titanium, nickel-based alloys) without causing embrittlement or corrosion.

• Excellent Wettability & Penetration: Formulated to spread quickly and evenly across the test surface, ensuring optimal coverage and maximum penetration into defects, leading to reliable and consistent results.

• Low Toxicity & Environmental Profile: Designed with user safety and environmental considerations in mind, typically featuring a low odor and a favorable health profile compared to some solvent-based alternatives.

• Met-L-Chek Quality: Manufactured by MET-L-CHEK, a globally recognized leader in NDT consumables, guaranteeing consistent product quality, batch-to-batch uniformity, and reliable performance essential for critical inspections.

• Comprehensive Compliance: Fully qualified and meets or exceeds the stringent requirements of numerous international and industry specifications:

  • AMS-2644 (Type 1, Method A, Sensitivity Level 3)
