GRAV® 14.5mm Glass Cleaning Plug

Cleaning your water pipe isn't easy when you have to use a spare finger or thumb to seal the pipe joint shut. That's where this 14.5mm GRAV Glass Cleaning Plug comes in handy.  Just place the plug in your pipe's 14.5mm female joint where your bowl attaches for an airtight seal to make cleaning easier. 

This glass cleaning plug can also serve as an air cork to block airflow for a water pipe with two joints. It's a dual-purpose piece that's made of premium boro glass. 

To use this cleaning plug, remove your bowl piece and place the cleaning plug in the joint.  Then add a cleaning solution or isopropyl alcohol to your pipe.  Hold your finger or thumb over the cleaning plug to secure it, then gently shake your pipe to clean out the crud.
