Measuring a Neck Before Ordering
Measure the inside diameter of the vessel mouth with a ruler or calliper. The No. 6 suits a mouth wider than its 20.0 mm base and narrower than its 24.5 mm top, and its 24.0 mm height leaves enough rubber above the rim to grip when pulling it out. If the mouth is close to the top figure, the No. 7 gives a firmer seat.
