15" Direct Inject Quad Diffuser Straight Tube

The 15" Direct Inject Quad Diffuser Straight Tube is made from premium borosilicate glass and features an interesting percolator system. The percolator system is created by four connecting diffusers which stem from the 90 degree female joint at the base. The female joint is a 90 degree 18.8mm dewars joint which is reinforced to the water pipe for added strength. This bong stands 15 inches tall with a thick chamber where the percolator system resides. Equipped with an ice pinch, you are able to put ice cubes to further cool down the smooth for a smoother hit as it is the last thing it will come in contact with before leaving the mouth piece. A blue colored lip and diffuser system give this tall water pipe a nice touch. Attached to the female joint is a 18.8mm flower bowl.
