A sealing device, which is simple in design, reliable in operation, and easily manipulated by remote handling equipment, is described for a vacuum apparatus. The device consists of an open receptacle perforated by an open-ended stand pipe adapted to communicate with the apparatus. The receptacle is provided with an intereal seating, a sealing cap insertable into the receptacle so as to surround the open-ended portion of the stand pipe, and a resilient seal between the cap and the receptacle seating. When the stand pipe is placed in communication with vacuum and with high density liquid in the receptacle, the sealing cap is urged by ambient pressure on to the seal and together with the high density liquid seals off the stand pipe end. The resilient seal is attached to the sealing cap. The upper end of the sealing cap is transparent. (N.W.R.)
