Description
The Glass Diffuser Coupling 18.8 mm (11 cm) is designed to enhance airflow and filtration in water pipes. Made from durable clear glass, the built-in diffuser helps break smoke into finer bubbles, resulting in smoother and cooler draws. With a standard 18.8 mm joint and an 11 cm length, this coupling is compatible with many glass bongs and is easy to install, remove, and clean—ideal as a replacement or functional upgrade.
