Where the 20/15 mm Taper Fits
Measure the inside of the neck first: this stopper suits any bore from 15 mm up to 20 mm. Seat it with a gentle turn rather than a hard push, and stop while some rubber still stands above the rim to grip. Should a tube need to pass through it, bore a hole with a borer matching the tube diameter, because the rubber springs back and tightens around the glass.
