ABSTRACT:
An improved system for effecting working access into sealed enclosures, such as glove boxes. The sytem includes an elongated arm-length sleeve, one end of which is sealed in a port fitting in the wall of the chamber and the other end of which is fitted with a replaceable glove. The elongated sleeve is preferably tapered from shoulder to wrist and of corrugated or convoluted structure for easy extension and retraction. The porthole fitting is preferably elliptical to maximize working access to the chamber. The inner end of the sleeve is fitted with a wrist bushing in which a glove supported on a deformable ring may be fit in sealed relation. The glove may be replaced with a further glove supported on a separate deformable ring without disruption of the sealed relationship.
