CF-4H-950F Coupling fluid for high temperatures

Made in the USAThe c CF-4H-950F oupling fluid is a high temperature coupling fluid for ultrasonic wall thickness gauges. It enables accurate measurements on surfaces with an recommended temperature range from 316ºC to 404 ºC.

It provides coupling for high-temperature thickness gauging and will maintain acoustic coupling at high temperatures beyond 15 seconds to give ample time to obtain thickness readings. In most cases, the signal strength increases with time to the point of the couplant’s thermal decomposition.


  • Extended open time window for longer inspections or to optimize thickness readings at high temperatures
  • Excellent corrosion inhibition
  • Non-toxic, non-irritating formula


  • Supplied in 120 ml tube
  • Excellent corrosion inhibition
  • Very slow drying; allows for long-term coupling without reapplication
  • Temperature range from 316ºC to 404 ºC
