The Replacement Glass Bong Stem has a frosted glass grip part in the neck that is either 14mm or 18.8mm wide at the top, this should match the measurement of the hole in the bong that the downpipe sits in. The stem length is how far the stem extends below the frosted grip into the bong, so it is advisable to ensure that it is not too long for the bong that it is being used for or it will not sit securely.Smooth rip, easy to clean.
