Fast reliable method for visually inspecting and spot-checking surfaces of welds, exotic alloys or standard metals, highly stressed structural members, critical castings, shafts, gears, spindles, and any other hard part where identification of surface flaws is essential.

Detects flaws such as cracks, pin holes, welding laps and porousness either during manufacture or on site. A three part system. SFD-501C is a cleaner. SFD-502C is a dye penetrant. SFD-503C is a developing fluid that reacts with the dye in SFD-502C to show small cracks in the weld. Each part supplied in an ozone friendly 500ml aerosol.
