Where the No. 5 Sits in the Range
Each step in this series is a little larger at both ends than the one before. The No. 5 closes openings that fall between its 17.5 mm base and 22.5 mm top, such as wider tubes and the necks of small bottles. Where a thermometer or delivery tube has to go through the stopper, a bored stopper is needed instead.
