J Hooks have been making appearances on beloved scientific characters like the guys of Silicon Valley. The J Hook is most appreciated by collectors, but a must-have for every beginner. It’s versatile joint allows you transform the Sherlock-esque mouthpiece between bubbler, bowl, and nail so you can try a little of everything! Attach your favorite ash catcher (such as GRAV’s Phoenix) for bubbling portable water pipe secured by a sturdy keck clip. Dry herbs and concentrates can benefit from a J Hook. This GRAV J Hook features a 14mm or 18mm female joint -- opt for the size that lets you enjoy your current water pipe attachments, too! Precoolers, slides, and other add-ons each create their own unique experience. The resilient keck clip is included on the 8 inch to 10 inch silhouette. The J-Hook is always a hit with groups, and makes for a fun activity on solo occasions masterminding epic combinations.
