Couplant & Adaptors

Couplant

The use of couplant is almost always necessary to provide acoustic coupling between the transducer and the test piece. We offer various types of couplants to suit virtually all applications.

Part Number Description Volume Application B2 Glycerin 2 oz. (0.06 liter) General purpose, more viscous, and has a high acoustic impedance, making it the preferred couplant for rough surfaces and highly attenuating materials. D12 Gel Type 12 oz. (0.35 liter) For rough surfaces such as sand-cast metals and fiberglass layups, weld inspections, overhead surfaces, or vertical walls. H-2 High Temp 2 oz. (0.06 liter) Temperature range 0 ° (-18 °C) to 750 °F (400 °C) in many open environment applications when used per manufacturer’s recommended procedure.* SWC-2 Shear Wave 2 oz. (0.06 liter) Normal incidence shear wave, non-toxic, water soluble organic substance of very high viscosity.

*Typical UT flaw and thickness applications use thin couplant films in an open environment where the small amount of gas formed can dissipate quickly. However, if an unlikely couplant gas auto ignition flash is of major concern, this couplant should not be used above the auto ignition temperature.
