ABSTRACT:
A compact, easily used, high quality sealing plug for use with ultrasonic testing equipment which incorporates a single annular body with an indented diaphragm portion, two lips, an annular vertical wall extending upwardly from said indented diaphragm portion of said single circular body with two annular lips extending outwardly therefrom, one at the upper end of said annular wall and the other therebelow so that when said seal is in use, the upper lip will maintain a position above the insulation material in which the seal is placed, while the lower lip will be below said outermost surface, both lips counteracting each other to maintain tension therebetween and the present invention from becoming unintentionally dislodged from its location. Alternative embodiments of the present invention are also disclosed which include alternative lip arrangements for alternative sealing needs and desires. A handle is mounted to the uppermost portion of said seal to allow for removal and reinsertion into the insulation material being plugged. Insulation material is also affixed to the lower end of said annular body immediately below said indented diaphragm portion so as to maintain an insulation covering over the area which has been exposed for an electronic testing or the like.
