Ultrasonic Testing Couplants

NDT technicians turn to Magnaflux for ultrasonic testing couplants that enhance sound transmission in non-destructive testing. Our couplants make it easier to test movement of sound from the transducer to the test part, producing reliable non-destructive inspection results in flaw detection, thickness testing, flow metering and acoustic emission testing.

Why Choose Magnaflux Ultrasonic Couplant Gels?

Magnaflux offers a variety of couplants, including high-viscosity gels for vertical or overhead surfaces, as well as low-viscosity fluids for broader coverage and ease of application. Our products reliably eliminate air gaps, improving the accuracy and reliability of ultrasonic inspections.

• Excellent wetting properties for better coverage
• Low environmental impact with biodegradable options
• Non-corrosive for sensitive materials
• Dry slowly for slower, more detailed inspections

Our ultrasonic couplants are perfect for high-temperature, shear wave, nuclear testing, power generation, aerospace inspections and many more applications.
