SKL-4C Water-Based Visible/Fluorescent (Dual-Purpose) Penetrant, 5 gal, Pail

Specially designed for chemically sensitive plastic parts, and for leak detection. Red dye is a visible penetrant that is water based and water washable. Indications appear dark purple-red in visible light and fluorescent orange in ultraviolet light. This allows dual range flexibility in the inspection process. Can be diluted with water, although it is recommended that a dilution ratio of 1:1 is used for general purposes.
