ABSTRACT:
A device for sealing detachable components, such as gloves, windows or closure plugs, in the ports of rigid walled chambers, such as glove boxes. The sealing device permits displacement and replacement of a detachable component in place in such a port without breaking the seal to expose the interior of the chamber to the outside atmosphere, or vice versa. The sealing device is characterized by a hand hole bushing disposed in the port and secured to the chamber wall to define a passageway having a continuous sealing surface and a continuous adjacent groove for retaining a detachable component within the bushing. The detachable component is characterized by a deformable semi-rigid bead adapted to be snapped into the continuous groove of the bushing and a continuous channel holding an O-ring sealing element which engages the sealing surface of the bushing. The detachable component may be glove supported on a ring adapted to engage the cuff of the glove to permit work to be done within the chamber, or it may be a plug to simply close a port or it may be a window for viewing the inside of the chamber. The relation of the bushing and detachable component is such that, when a replacement component is to be installed, the detachable component to be replaced is forced inwardly into the chamber, maintaining sealing engagement with the bushing until the replacement component has entered into sealing engagement with the bushing.
