Phased Array Couplant

EchoPure is the couplant of choice for Phased Array UT Inspection (PAUT). EchoPure improves defect reproducibility by eliminating dry spots under the wedge and the resulting noise and artifacts. EchoPure is a water-free, water-soluble ultrasonic couplant that has a broad operating range, is slow drying and provides excellent transducer lubrication.

Forever Wedge Ultrasonic Couplant won’t dry, run, leach, or dissolve with water or couplants. It will stay in place for months or years until you decide to remove the wedge. Forever Wedge Couplant is not an adhesive and will not bond to the wedge.
