Browse our downstems collection.
Downstems connect a bowl to bong water, using length, joint sizes, and diffuser cuts to set water depth and airflow.
Measure total and usable length, outer joint, bowl joint, and angle before comparing diffusion.
Clean separately with a narrow brush and handle thin diffuser slits over padding.
Confirm how the seller measures length and match both connections—not only 14mm or 18mm.
