Our most popular general purpose couplant. -
Single packet powdered UT couplants provide an economical solution for travel, remote access inspections and storage limitations. EchoMix Single is a one-part (one packet) powder, easily mixed in ambient water in five minutes, providing a strong, continuous coupling film that adheres well to vertical and overhead surfaces. Single mix packet, one step mixing. -
Couplant for use with the Cygnus Single Crystal Transducers. Used between the membrane, and the probe face. -
Normal incidence shear wave transducers require a stiff, high viscosity couplant to support shear waves. Echo Shear Wave ultrasonic couplant transmits normal incidence (zero degree) shear waves, is nontoxic, water-soluble and easily applied and removed. A small amount of Echo Shear Wave Couplant should be placed on the face of the transducer or the test piece and then pressed into a thin layer. For optimum coupling, it is important that the couplant layer be thin. -
Echo Z+ is a high acoustic-impedance ultrasonic couplant. It increases acoustic impedance and decreases surface noise, making it ideal for very rough, pitted, corroded surfaces or tight-curved test objects, and concrete. Echo Z+ contains no VOCs, naptha, oil, hydrocarbons, silicones, petroleum distillates, dyes or fragrance. Contains a short term ferrous corrosion inhibitor. Echo Z+ contains glycerin and is intended to be removed from non-ferrous metal parts after inspection. -
EchoPure is an ideal couplant for very cold environment inspections and will not frost on test objects causing attenuation at temperatures as low as -60˚F/51˚C. EchoPure is also excellent for ambient and elevated temperature use such as warm welds up to 350˚F and on pipe in the desert summer sun, where slow evaporation and long inspection windows are desired. Available in 3 viscosities: Low viscosity fluid, medium viscosity gel, and high viscosity gel. -
Echo 8 ZH is intended for ultrasonic coupling where elevated temperature, surface roughness or long coupling time frames (such as Ultrasonic Flow Meters) present difficulties. It maintains its paste like viscosity throughout its effective operating range for extended time periods. -
The first and only high temperature ultrasonic couplant that has an auto-ignition temperature and flash point above 1300ºF. With no minimum operating range, no residue, less smoke and no auto-ignition under 1300ºF, EchoTherm Extreme is an ideal couplant for port inspections. EchoTherm Extreme is a high viscosity paste that adheres well to the transducer. -
A high temperature thickness gauging and corrosion testing couplant that has an operating range of 200°F to 1000°F (93 to 538°C ) and an auto-ignition temperature of above 1300°F (704°C) -
Product discontinued RFS has limited stock remining EchoTrack is the lowest price, high-performance ultrasonic couplant with improved resistance to corrosion salts and is formaldehyde and glycol ether free. -
SoniX provides a strong, lubricious, water-soluble coupling film as a universal ambient temperature NDT ultrasonic couplant. -
VersaSonic is the most versatile couplant, from high temperature to turbine rotors to extreme weather inspections. VersaSonic is a low-toxicity, biodegradable couplant that does NOT contain peanut oil. -
Cygnus have replaced the UCA-2 with the UltraSoniX couplant. UltraSoniX is now supplied as standard with all Cygnus gauges.
