The Forever Wedge UT Couplant is a high-viscosity fluid for phased array and angle beam wedge attachment and for coupling delay lines. It won’t dry, run, leach, or dissolve with water or couplants. It will stay in place for months or years until you decide to remove the wedge. It's not an adhesive and will not bond to the wedge.

Reliable long term coupling of wedges to transducers is a critical technology to insure reproducible results and eliminate recoupling probes to wedges during inspection.
