The GRAV 3.3-inch Fission Downstem is the short version of GRAV's 19mm-to-14mm glass downstem. It fits into a 19mm downstem joint and has a 14mm receiver for a male bowl or banger, so it suits smaller beakers and straight tubes where a longer stem would sit too close to the base.
The fission holes are formed with a tungsten rod while the glass is hot, giving them smooth edges that GRAV says resist clogging. They break each pull into small bubbles for smoother diffusion through the water.

Choosing the right length
Measure the downstem you have now from the bottom of its frosted joint to the tip, since listed lengths leave out the joint. If it is about 3.3 inches, this is your size. If it is longer, see the GRAV 4.5-inch Fission Downstem. GRAV makes both for beaker-base and straight-base pipes with an angled downstem joint.

3.3-inch Fission Downstem FAQ
Will it fit a 14mm downstem joint?
No. The top of this downstem goes into a 19mm joint. The 14mm part is the receiver for your bowl.
How much water should I use?
Enough to cover the fission holes by a little. A short downstem needs less water than a long one.
Fits the GRAV 14mm Cup Bowl, the GRAV 14mm Triple Pinch Bowl and other 14mm male bowls. Browse all parts and replacement pieces.
