Magnaflux® MAGNAVIS® 01-1580-77 7HF Magnetic Particle Oil-Based 10.5 oz Aerosol

A highly sensitive oil-based magnetic particle aerosol for non-fluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts. 7HF provides clear, strong indications due to the heavy buildup of the highly magnetic particles. The convenient aerosol packaging is ideal for field testing, spot inspections, and places where bulk processing is impractical, and the wide spray pattern makes it easy to cover large areas for faster processing during remote inspections of tubing, piping, and large structures. 7HF is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity.
