Soundsafe

High Performance Ultrasonic Couplant

Soundsafe® is a medium-viscosity, thixotropic ultrasonic couplant formulated for general‑purpose NDT applications. Engineered for high-performance flaw detection, thickness gauging, flow metering, and acoustic emission testing, it provides exceptional surface wetting, superior corrosion protection, and compatibility with nuclear- and aerospace‑grade inspections—all in a non-toxic, silicone‑free formula trusted by industry leaders including Pratt & Whitney.

Features

Wide specification approvals (API, ASME, ASTM F519/F945, AWS, PWA 36604/PMC 4385)
Excellent surface wetting and fast, even coverage
Thixotropic gel adheres to vertical and overhead surfaces without dripping
Highest level of corrosion inhibition among Magnaflux general-purpose gels
Increased acoustic impedance reduces surface noise
Provides good transducer lubrication
Slower drying time extends inspection periods
Non-toxic, non-irritating; suitable for hydrogen embrittlement testing
Approved for aerospace and nuclear use (Pratt & Whitney)

Applications
