Clear Glass Hole Diffuser Downstem 18mm to 18mm

Description

Replace a worn or broken piece with this clear glass bong downstem, offered in multiple lengths. Refer to the sizing image below to choose the length that suits your setup.

This downstem has 18mm to 18mm joints. It is designed for glass bongs with an 18mm female joint and accepts an 18mm male bowl on the inner end. Confirm both joint size and downstem length before ordering.

Made from clear borosilicate glass, this diffuser downstem uses precision-cut holes to disperse smoke into smaller bubbles as it passes through water. The transparent design keeps the look clean while making it easier to see the piece during use and cleaning.
