The rubber cone provides a seal between the filter flask and the Buchner Funnel - the seal is not formed at the stem, but at the tapered base of the funnel as it is pushed down into the cone located in a filter flask neck. Choose the rubber cone size which fits part way into your flask neck e.g. a 23mm ID flask neck requires a rubber cone with 19mm bottom dia. & 27mm top dia.
