GRAV 14mm Fission Downstem 3.3″

The GRAV 14mm Fission Downstem measures 3.3 inches in length. This shorter length is suited to smaller beaker bongs and water pipes that have a shallower water chamber and require a shorter downstem to reach just below the waterline. Choosing the correct downstem length for your bong is important for achieving proper smoke diffusion and preventing splashback. Measure your current downstem or check your bong specifications to confirm the 3.3-inch length is the right fit.

The GRAV 14mm Fission Downstem 3.3″ fits into a 19mm female bong joint at the lower end and accepts a 14mm male bowl or banger at the upper end. Before purchasing, verify your water pipe has a 19mm female joint opening. The 14mm female top joint is compatible with the majority of standard 14mm male herb slides and bangers. This makes it suitable for both dry herb and concentrate sessions on compatible water pipes.

The GRAV 14mm Fission Downstem 3.3″ and 4.5″ versions use the same borosilicate glass construction, fission hole design, and joint sizes. The only difference is the overall length. The 3.3-inch version is designed for smaller or more compact beaker bongs, while the 4.5-inch version suits larger water pipes with a deeper water chamber. Selecting the correct length ensures the fission holes sit below the waterline for proper diffusion and smooth hits from your bong.

The fission holes in the GRAV Fission Downstem are drilled using a tungsten rod while the borosilicate glass is still hot during manufacturing. This creates smooth, rounded hole edges rather than sharp or rough ones. Smooth edges are less prone to accumulating resin and clogging over time compared to downstems with sharp-edged holes. The fission holes also break smoke into many small bubbles as it passes through the water, increasing the surface area of smoke in contact with water for more effective filtration.

The GRAV 14mm Fission Downstem 3.3″ is compatible with any 14mm beaker or straight-based water pipe that has a 19mm female joint and an angled joint configuration. The 3.3-inch length is best suited to smaller or compact water pipes. If your bong uses a different downstem diameter, a non-standard joint, or requires a longer downstem, this model may not be the correct fit. Confirm your bong specifications before purchasing to avoid compatibility issues.

To clean the GRAV 14mm Fission Downstem 3.3″, remove it from the bong and soak it in isopropyl alcohol for 15 to 30 minutes. Plug the ends with your fingers or small caps, add isopropyl alcohol and a small amount of coarse salt, then gently shake to help remove stubborn residue. Rinse thoroughly with warm water afterward. The smooth-edged fission holes are designed to minimize clogging, making routine cleaning straightforward. Regular cleaning after sessions keeps the downstem performing at its best.
