Glasscity Inside-Cut 18.8mm > 14.5mm Slitted Diffuser Downstem

Instantly personalize your favorite bong with this glass inside-cut 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 inside-cut 18.8mm > 14.5mm glass-on-glass joints allow you to add powerful diffusion to any piece with an 18.8mm joint, and will fit any 14.5mm 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 Inside-Cut Slitted Diffuser Downstem is available in blue, green and amber and in several different lengths, so there is bound to be one that fits 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.
