A brand name alone does not guarantee compatibility. Match the bong joint, bowl joint, and measured length before adding this downstem to your bag.

How to measure a bong downstem from the top lip of the ground joint to the end of the downstem

How to measure

Measure From the Top Lip

  1. Remove your current downstem from the bong.
  2. Measure from the top lip of the ground joint to the very end of the downstem.
  3. Choose the matching length option above. The tip or diffuser openings should sit underwater without touching the chamber.
Do not measure the full glass from its highest point. The usable length starts at the top lip of the ground joint.

Compatibility checklist

Check All Three Measurements

1

Bong Joint

The outer joint on the downstem must match the ground joint on your bong.

2

Bowl Joint

The inside opening must match your bowl. A 14/18mm downstem takes a 14mm bowl and fits an 18mm bong joint.

3

Usable Length

The diffuser must reach below the waterline while clearing the bottom and side of the chamber.

Downstem Fit Questions

How do I measure this replacement downstem?

Measure from the top lip of the ground joint to the end of the downstem, then select the matching length variant.

What does 14/18mm mean?

The 14mm opening accepts a 14mm bowl, while the 18mm outer joint fits an 18mm bong joint.

Will this fit any bong from the same brand?

No. Models from the same brand can use different joint sizes and lengths. Confirm all three measurements.

How far should the downstem sit in water?

The tip or diffuser openings should sit below the waterline without touching the chamber wall or bottom.
