Frequently Asked Questions

Will this fit my bong?
This stem features a standard 14mm male joint, so it fits any water pipe with a 14mm female joint. Check your rig's joint size before ordering — it will not fit an 18mm joint.

How do I clean this glass attachment?
Since it is a small glass piece, you can easily remove it from your water pipe and soak it in warm water or a standard glass cleaning solution to clear out any leftover residue.
