Abstract: A testing apparatus to test electrical insulating gloves is disclosed. The apparatus is a cylindrically shaped, grooved housing unit with an air outlet and an air valve that attaches to a glove inflator, such as the G-I Glove Inflator, to allow testing of various sizes of electrical insulating gloves of varying voltage ratings. The electrical insulating glove is stretched over a groove and held in place by a stretchable o-ring, thereby allowing the glove inflator to inflate the glove to a sufficient size to enable to electrical worker to inspect the glove for damage and leakage, which, if present, would decrease or eliminate the effectiveness of the glove's insulating characteristics.
