    The Echo Ultrasonic Forever Wedge Couplant is a high viscosity fluid for phased array and angle beam wedge attachments and coupling delay lines.

    This reliable and long-term couplant will stay in place for months or years and is resistant to water, heart, and light. Despite its durability, the FW-02 is easy to remove. Overall, the coupling of wedges to transducers is an essential technology to ensure reproducible results and to reduce recoupling probes to wedges during an inspection.
