Convert the size of your favorite, or least favorite, bong or rig with this GRAV Connection Joint Adapter.
This adapter works through either of its two joints: it has a 14mm Male joint and a 19mm Female joint.
- Use the 14mm Male joint to change your 14mm female connection joint bongs into 19mm female joints.
- Attach the 19mm Female joint to your 19mm male jointed bongs to change them into 14mm male joints.
