Abstract
Some O-rings can include internal flaws that can eventually lead to failure of the O-rings during use. In order to scan an internal structure of an O-ring, the present disclosure includes an apparatus with an apparatus body to which an O-ring support and a transducer assembly are attached. The transducer assembly includes an ultrasound generator that transmits ultrasound toward the O-ring to generate reflections toward an ultrasound receiver. The apparatus includes a display for comparing ultrasound receiver data with expected data. It is determined whether there are reflections of the ultrasound transmissions off of at least one internal surface within the O-ring.
