Diffuser Downstem. These downstems have small holes at their ends to diffuse the smoke as it enters your bong. The clear glass with colored logo gives it a clean look.

Stem Measurement Details (photo attached to show measurement may show a different downstem for reference purposes) - Brand-By-Brand: From our experience, the STANDARD method of measuring Ground Joint Stem length is generally to measure the amount of glass that's below the 'joint' to measure how deeply into the bong the stem goes, beyond that joint... SO, generally they are measured from the bottom of the ground glass (frosted) joint to the absolute bottom of the stem. Unfortunately this rule is complicated by some brands that do things a little differently, so the following is our understanding of the stem measurement protocols of our most popular glass brands. 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. If you have any uncertainty regarding measurement please don't hesitate to contact us at email@example.com for clarification or help of any kind!
How each glass company measures their Glass-On-Glass (a.k.a. Ground-Glass) Joint Down-Stems: Cheech: Measured from bottom of ground-glass joint to bottom tip. GEAR: Measured from tip to tip (overall length) - therefore, about 2.5cm / 1" higher a number than the standard method would give. HOSS: Measured from TOP of ground-glass joint to bottom tip. Illadelph: One option - fits both beakers and straights (and Micro-Mini fits Micro-Minis). Infyniti: Measured from top of ground-glass joint to bottom tip. Nice: Measured from bottom of ground-glass joint to bottom tip. NoName: Measured from bottom of ground-glass joint to bottom tip. OG: Measured from bottom of ground-glass joint to bottom tip. Preemo: Measured from bottom of ground-glass joint to bottom tip. ROOR: Measured from TOP of ground-glass joint to bottom tip.
Hoss is one of very few brands of Glass-On-Glass fitting downstems that measure with the overall length (or more like the distance from TOP of joint to bottom tip of stem) which seems from our measurements to be about 2cm longer than the normal measuring method of bottom-of-joint-to-tip gives. So, a 10cm HOSS measurement here would represent the equivalent of 8cm in our normal measuring method, for example.
