Glass adapter / reducer 18.8 → 14.5 mm with diffuser
Expand what your bong can do with this sleek glass reducer. It steps an 18.8 mm ground joint down to 14.5 mm, so you can comfortably run 14.5 mm bowls and accessories in a bong with a larger socket. The lower end features a diffuser – fine slits that break the smoke into a stream of tiny bubbles for cooler, smoother and better-filtered hits with less harshness.
