Adapter Diffuser 18.8/14.5 9-cm

The Adapter Diffuser 18.8/14.5 (9-cm) is a precision-ground glass converter that bridges your 18.8mm (SG19) bong joint and standard 14.5mm (SG14) bowls. At 9 cm it reaches the ideal depth to deliver cooled, filtered smoke, while its slitted diffuser tip breaks each draw into fine bubbles for smoother, gentler hits and better filtration. The male 18.8mm end seats firmly into your bong, and the female 14.5mm receiver accepts any compatible bowl or downstem, letting you mix and match your favorite glass. Made from thick borosilicate glass for thermal durability and a clear look, it installs in seconds with an airtight seal and cleans easily. Whether upgrading an older rig or expanding options, this adapter is the versatile, cost-effective path to a customized smoking experience.
