Magnaflux ULTRAGEL-II (355ml-Ctnr)

Additional Product Information

Overview

Ultragel II is a high-performance ultrasonic couplant designed for precision nondestructive testing (NDT) in aviation and MRO applications. It is widely used for flaw detection, thickness gauging, flow metering, and acoustic emission testing. Teams rely on Ultragel II for its consistent performance, slow drying time, and superior corrosion protection, making it ideal for vertical, overhead, and rough surface inspections.
