Ultrasonic Couplant

To meet our local industry's specific requirements, Western manufactures a specialty line of Ultrasonic Couplant. This includes a -40°F / -40°C Couplant, which is ideal for use with Portable UT Equipment year round. This Couplant maintains its low viscosity above +40°C / 105°F as well. Other features of our -40° Ultrasonic Couplant are the addition of a UV tracer, to ensure full removal can be inspected. After dry wiping the work piece, -40° Ultrasonic Couplant is removed with a dampened cloth or industrial wipe. For flaw detection, -40° Ultrasonic Couplant can be diluted with water to raise its viscosity.

Couplants that are water free, for High Temperature Stainless Steel Service, are also offered by Western, and have been aptly named No H2O UT Couplant. The viscosity of No H2O UT Couplant remains constant from -40°F / -40°C through to 400°F / 205°C. No H2O UT Couplant can be diluted and fully removed with the use of a Stoddard Solvent (Varso®, Bayol®, Naptha, etc.)
