PCT No. PCT/SE82/00133 Sec. 371 Date Dec. 15, 1982 Sec. 102(e) Date Dec. 15, 1982 PCT Filed Apr. 23, 1982 PCT Pub. No. WO82/03951 PCT Pub. Date Nov. 11, 1982.A method and tool for sealingly inserting an elastic body in a cavity in a wall in which the cavity has a smaller size than the initial size of the body. A first tubular end portion of the tool is inserted into the cavity and an elastic body is accommodated in a second larger tubular end portion of the tool such that the elastic body rests on a tapered portion which joins the tubular end portions. The second tubular end portion is then closed and pressure fluid is supplied into the second tubular end portion to compress the elastic body and cause it to pass from the second tubular portion into the first tubular portion and then to exit from the first tubular portion into the cavity. The elastic body expands as it exits from the first tubular portion to tightly engage the wall around the cavity and to expel the first tubular end portion from the cavity.
