sheath 2 to the point where it snugly abuts flange 10 as well as sheath 2 the sealing member 5 could also be securely bonded to either or both flange 10 and sheath 2 the sealing member could have a hemi torus shape with a back surface conforming to and abutting flange 10 which could facilitate a bond therebetween without severe sacrifice in the flexibility of a full torus sealing member flange 10 should be mounted at a slight angle of approximately 15 u00b0 from normal to the sheath 2 depending on the curvature and length of tube 3 flange 10 could itself have curvature and could be mounted to allow a slight degree of pivot not shown instead of a flange other sealing member support structures can be used such as a conventional coil spring apparatus when the nozzle 1 is inserted into a fillpipe 11 as shown in fig2 the sealing member 5 seats firmly against the mouth 12 of fillpipe 11 and one or more latches 13 mounted on the sheath 2 engage the lip 14 of the mouth 12 to maintain the seal and to retain the nozzle 1 within the fillpipe 11 the latches 13 and sheath terminus 4 are tapered to provide easy entry into the fillpipe the latches 13 could be replaced by a conventional collar or by a half collar on the lower periphery of the sheath the sealing member can be used on a nozzle having a vapor recovery conduit means which is external to a receptive fillpipe such as the conduit means described in the aforementioned u s pat no 3 866 636 an embodiment of of the sealing member on a.
