The Megger 512117 pneumatic glove tester is a hand pump that inflates disposable gloves to check for leaks. It can be used to test gloves made from a rubberized material, such a latex or neoprene, that have up to a 5" cuff diameter. A check valve on the tester can be closed to keep the glove inflated for inspection. The tester comes with two elastic sealing rings to hold the glove on the pump, and the rings are covered with fabric to help keep the glove from ripping due to friction between the ring and the glove. The tester is 5.5" long and 5" in diameter.

A rugged molded air pump conveniently tests all types of rubber gloves with a cuff diameter of 5 in. (127 mm) or less. A built-in check valve retains pressure within the glove as long as desired. This Biddle Tester is provided with two fabric-covered elastic sealing rings.
