Abstract
A hermetically sealed connector for a glove box and a method for exchanging such connectors in which leakage of radioactive material from within the glove box is minimized and an auxiliary glove box is not needed to exchange the connectors. The connector is formed as a cylindrical member having a flange portion hermetically sealed to a packing provided in a through hole in the wall of the glove box. To exchange connectors, a nut is removed from the outer end of the old connector and a tube is screwed thereto. The other end of the tube is fitted to the inner end of the new connector. The tube is then shoved through the packing until the flange of the new connector aligns with the packing. The tube is then removed from the inner end of the new connector and a nut is screwed on in replacement for the tube.
