Magnaflux MV-740 Water-based Visible Magnetic Particle Suspension

USD $20.33USD $187.65

Magnaflux MV-740 water-based visible magnetic particle suspension is a highly-sensitive water-based magnetic particle fluid for non-fluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts.


MV-740 provides clear, strong indications due to the heavy buildup of the highly magnetic particles. The product is ready-to-use, so no dilution is required.  MV-740 is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity.


Eco-friendly Profile

  • Environmental-friendly water-based formula
  • Packaging made from post-consumer recycled plastic and can be recycled after use
