10mm Female Fitting for 10mm Bowl

See photos for details about measuring downstems. For these, "glass on glass" also known as "ground glass joint", downstems, the inches measurement does NOT represent the overall length of the entire glass piece, but is a measurement of the stem from the bottom of the ground glass joint to the bottom tip/end of the entire stem (and thus how deep into your water-pipe the downstem will reach beyond the ground glass joint). For metal stems and the more traditional / older style plain glass (also known as "9mm" bowl stem size), the measurements are different - we use a measurement of the overall length of the entire stem. While this apparent variation of measurement methods may seem somewhat confusing to some, it is of course the most logical method since it uses the "important" measurements (for ground glass joints there can be variation in measurements and fittings ABOVE the bottom of the joint, so the important measurement is the distance BELOW it). Please also note that, as with all blown-glass items, there is always a little variation from one stem, and one measurement, to the next - so please allow for a slight variation in measurement and don't expect the numbers to be EXACT.
