Black Leaf Silicone Reducer Stem Diffused


Product Description

The Black Leaf reducer downstem is made out of silicone, making it virtually unbreakable. This downstem converts 18mm joints to a 14mm joint, it significantly shortens the glass sticking out from your bong producing a neater look. It hosts a six hole diffuser** to help break down and cool the smoke, provide a great smoking experience.

Bring some eye-catching colour to your bong or rig with this Black Leaf silicone reducer stem diffused. You get your choice of several colours to match your setup, and the silicone construction prevents breaking. This diffuser stem works with 18mm joints and reduces to 14mm so it will fit 14mm bowls / cone piece.

Resin doesn’t cling to the interior walls of the downstem, making it easy to clean. You the option to change the length to suit any bong or rig, and the diffuser holes at the bottom of the stem provide better bubbling for a smoother hit. The silicon design fits snugly to the joint, preventing any air leaks during your rip.

This is a great option to keep on hand as a spare in case you break your glass stem, while you wait for the replacement to arrive. Also a great option if you have clumsy friends.
