Echo Ultrasonics VersaSonic® Multipurpose High & Low Temperature Ultrasonic Couplant
SKU: VS-02-2
VersaSonic® is a versatile ultrasonic gel couplant engineered for flaw detection, corrosion mapping and thickness measurement across a broad temperature range of -10°F to 700°F (-23°C to 371°C). The VS-02-2 high-viscosity formulation is supplied in convenient 2 fl oz / 59 mL metal tubes.

Echo Ultrasonics VersaSonic® is a multipurpose ultrasonic couplant developed for reliable acoustic coupling during ultrasonic inspections in demanding industrial environments. Its broad operating temperature range makes it suitable for applications involving heated components, low-temperature equipment and variable outdoor conditions.
The formulation provides rapid ultrasonic response without plastic powders that can delay sound transmission. It also functions as a high-temperature transducer lubricant and delivers corrosion-inhibiting properties for ferrous materials.
VersaSonic is available in medium and high viscosities. The high-viscosity formulation used in the VS-02-2 configuration is designed to remain on transducer faces, curved surfaces and areas where controlled couplant placement is important.

Key Features
| High-viscosity formulationThe high-viscosity gel remains in place on surfaces and transducers, supporting controlled ultrasonic coupling during inspection of curved, rough, vertical and difficult-access components. |
Broad operating temperature range
Designed for ultrasonic testing between -10°F and 700°F (-23°C to 371°C), providing flexibility for inspections in freezing weather and on elevated-temperature industrial components.
Instantaneous ultrasonic response
The formulation contains no plastic powders that delay ultrasonic conduction, allowing technicians to obtain readings without the waiting time associated with some high-temperature couplants.
Transducer lubrication
VersaSonic provides effective high-temperature lubrication at the transducer-to-surface interface, helping reduce wear during ultrasonic inspection.
Corrosion-inhibiting properties
Provides long-term corrosion inhibition for steel and cast iron while remaining compatible with other metals and most plastics. Residual couplant can generally remain in place unless later manufacturing operations require removal.
Suitable for harsh environments
Supports ultrasonic inspections under challenging field conditions, including rain, mud, snow and temperature variations.
Low environmental impact
The low-toxicity, biodegradable formulation contains no perfluorocarbons, silicones, peanut oils or tree nut oils.
VersaSonic Product Family
VersaSonic is offered in multiple package sizes for portable field inspections and larger industrial applications.

Application and Handling
Applying the couplant
Dispense an appropriate amount directly onto the transducer contact surface or inspection area in accordance with the ultrasonic testing procedure. Ensure adequate acoustic contact throughout the measurement.
High-temperature inspection safety
Follow the manufacturer-rated operating limits for the couplant and ultrasonic probe. Confined spaces and inspection ports can be significantly hotter than exposed surfaces. Verify actual contact temperature before inspection.
Cleaning after inspection
Residual VersaSonic can normally be wiped away with a paper towel or cloth. Where complete removal is required, dish detergent and water or a suitable chemical degreaser may be used.
