Abstract
An improved gasket sealing motor leads which extend from the interior of an electric motor enclosure. The gasket is provided with one or more resilient, conical bushings whose diameters extend through a wide range of lead diameters. By severing the bushings at an appropriate point, round apertures are formed through which the leads can be pulled and sealed. The flat portion of the gasket which surrounds the bushings is secured to the motor enclosure in a conventional manner.
