The 9mm Series from Illadelph Glass represents the most heavy-duty, extra-thick, most durable water pipe that they have to offer. Using glass that is 80% thicker than their standard production water pipes, the 50x9mm (fifty by 9) tubes have all of the features that we have come to expect from Illadelph Glass: An extra-thick 19/22mm joint for the colored down stem and a matching extra-thick 14mm single-hole slide. Even the base of the pipe gets the 9mm treatment to help prevent breakage. This is definitely a water pipe that has been designed to last for years to come. Available in either short, medium or tall heights (17”, 19” and 21”) and in 12 different colors, choose your favorite today!
