Glasscity Slitted Diffuser Downstem | 18.8mm

Instantly change the appearance of your favorite bong with this colorful glass slitted diffuser downstem by Glasscity. The slits divide the smoke and create loads of bubbles, allowing the smoke to cool significantly better than with an open-end downstem.

The 18.8mm glass-on-glass joints allow you to add powerful diffusion to any bong with an 18.8mm joint, and will fit any 18.8mm glass-on-glass slide bowl or attachment with a male joint. The Glasscity logo is placed on the side of the diffuser downstem.

The Glasscity Slitted Diffuser Downstem is available in blue, green and amber and in several different lengths, so there is bound to be one available that is perfect for your bong. If you're not sure which length you need, have a look at the image that shows you the proper way of measuring the length of your downstem.
