ABSTRACT:
A couplant material for establishing a sonic path of good acoustical impedance between an ultrasonic transducer housing and its crystal, and the housing and a pipe to which the housing is attached. The material is capable of being easily applied at room temperature and withstanding vibration and thermal cycling from cryogenic temperatures to over 500.degree. F. while substantially maintaining its chemical, physical and acoustical properties. A preferred couplant material is a polytetrafluoroethylene grease or perfluoropolyalkylether grease, which have been used previously as lubricants.
