Magnaflux Ultrasonic Couplant Echogel

Economical Ultrasonic Couplant

Echogel® is an economical, basic-use couplant for ultrasonic inspections, like flaw detection/sizing and thickness gauging, where salt cake or metal corrosion salts are present. It provides good corrosion inhibition and resists viscosity breakdown on salt-caked boilers and other corroded materials.

Echogel comes in two different viscosities, Echogel 14 which is a thin, flowable gel and Echogel 20 which is a medium-thick gel.


  • Enhanced surface wetting to quickly cover oily or dirty surfaces
  • Maintains viscosity on corrosion or salt cake
  • Good corrosion inhibition
  • Silicone free
