This 3.5" Tree Perc Diffused Downstem can be used to replace any downstem on the shorter bongs in our store and can be paired with any 14mm bowl piece. The reinforced 6-arm tree perc with horizontal slits encourages optimal smoke percolation and water filtration. These features help break up smoke so that more water contact is made, creating an even smoother smoking experience. 

Note: Our downstem lengths are measured from the bottom of the joint to the tip of the downstem. The full length of the glass piece will be between 1"-1.5" longer including the glass on glass joint.

This product is intended for tobacco and other legal herb use only.

    Simple, yet effective

    Posted by Danny Horn on Jan 13th 2020

    I've been browsing this store for a while and finally decided to test the waters with a small buy. Couldn't be more impressed with how this little $15 downstem changed the function on a bong I've had for ages. It is a bit trickier to clean than a regular downstem, but the extra maintenance is worth it. Way better than buying a whole new bong.
