ROOR Non-Diffuser Downtube

Get this non-diffuser downtube as a replacement or spare for the standard downstem that comes with your ROOR bong, or try it when you want old-school snap rather than a soft, bubbly pull. ROOR's sturdy, high-grade glass downtube is available in 14.5mm or 18.8mm, in a variety of lengths, so choose your joint size and desired size from the drop down menus when ordering. (Remember to measure from the top of the middle joint to the bottom end of the tube!)

Founded in the 1980s by German glass-blower Martin Birzle, ROOR produces high-end premium borosilicate glass bongs and smoking accessories, many of which you can find right here on our site!
