This is the old-school classic clear replacement slide for the standard 12mm slide downtube. This 9mm slide bowl is slightly thicker than the standard stock bowl included with most basic or cheaper water pipe purchases. This is not a glass-on-glass ground joint accessory. This will not fit in a 14mm or 18mm glass-on-glass downstem. Comes in a standard 3 to 3.5 inch length. Each slide bowl comes with a black O-ring for an air-tight seal.
