14.5 mm (M) to 18.8 mm (F) Adapter
A glass adapter featuring 2 GonG joints – a 14.5 mm male one and an 18.8 mm female one. The adapter allows you to connect two pieces together, one of which features a 14.5 mm female joint, while the other has an 18.8 mm male one. This is a perfect solution, for example, if you have a water pipe with a 14.5 mm joint (female type) and would like to plug in an accessory with an 18.8 mm male glass joint.
